New to the Gameboy 'Chiptune' Scene?  Or maybe your still trying to get to the bottom of what this whole Chiptune thing is?  No matter your situation, by the end of this Instructable, I can promise you'll be a pro!

Relatively new to the 'LSDJ' scene myself, I was baffled when I tried to put together my first DMG- so many options, yet so little troubleshooting guides!  Seeing the need for more structured tutorials, i planned to put my own together- that is, after i could figure everything out!

Fast forward a few months, and here I am!  A bit more experienced in working with the Gameboy, and electronic skills increased, I started working on the group of tutorials within this Instructable to help others conquer the DMG, helping you make an awesome, custom instrument, all of your own!

Now, of course it would help to have a little background in electronics, but for those of you just starting out, have no fear!  I've made sure to document each step, taking plenty of pictures along the way!  I can almost guaranty you'll have no trouble!  (and, of course, if you ever have trouble, just comment!  I'll be sure to help!)

Now follow me, on a journey, as you and I turn our ordinary ol' Gameboys into something truly worth making music on! 


Oh! but before we get started: 
If you like the Instructable, or are following it to build your own DMG- Please consider voting for it as a winner in the Music Instruments Contest!  It's just a quick click- and I'd really Appreciate it!  Thanks!

Thank you guys so much for your votes!  It's because of you i placed in the Musical Instruments Contest- i really 
appreciate it!


Update (9/30): Having finally finished the two main builds featured, i thought i'd come back to add some pics- as well as go more in-depth about my new found friend- the Pocket!

Step 1: Types, Terminology...

For those of you new to Gameboys and/or Chiptunes, it may not be the worst idea to take a look though some of the strange new vocab you'll be seeing both in the Instructable, and out 'n' about in Chiptune forums!  (Clicking the link will open a new tab with an example!)

- Chiptune: As the name implies, a Chiptune is an analog or emulated tone created by some kind of 'chip'- or rather an IC.  In most cases though, these tones are brought together forming music!  Think Atari and NES, or in our case, Gameboy!

- Chrystal/Oscillator: A Fancy little part that essentially vibrates electrical signal that can be honed to a very accurate frequency.  Commonly used to keep time, you'll see later we can mod the Gameboy's to make it run quicker/slower!

- Clearboy: DMG's that once/still are clear.  Most are painted from the inside, creating an awesome effect!  (check out step five to se my Clearboy!)

- DMG: A common nick-name for your standard original Gameboy, the letters DMG come from the first part of the model number's printed on each Gameboy.

- Gameboy Advance/SP/Micro: Other types of Gameboys, not normally associated with Chiptunes, as they're new aged ways of audio processing sound no where near as good using LSDJ,as the old ones!

- Gameboy Color: A bit smaller, and with a colored screen, the Gameboy Color is still very mod-able!  Pay close attention though, as somethings, such as the backlight require completely different parts!

- Gameboy Pocket: A smaller, model of the original DMG, that contains a much more clear screen.  These guys are almost identical in circuitry to the original Gameboy, so many DMG mods will work on here too!

- LSDJ: Unlike the psychological drug, LSDJ, or Little Sound DJ, is an amazing little program that's most common in the Gameboy Chiptune world for making music!  Check Step 14 for more information!

- PS/2: An older connector for keyboards and mice, you can use a PS/2 keyboard to play sweet tunes on LSDJ like a piano!  Checkout Step 12 for more info!

-Tri-Wing Screwdriver: An uncommon screw type, that also just happen's to be Nintendo's favorite!  Be sure to pick on of these up before we begin!

*Confused on a term and it's not here?  Comment!  This list will be updated quite frequently!*

Step 2: ... and Testing!

Here we'll cover testing/troubleshooting- have a problem with your DMG, and just not quite sure what it is?  This step is for you! Hopefully we'll get that baby running like new!

Due to their age, and the age of people who've owned them, there's a pretty good chance the DMG you have has some kind of issue. This is by no means the end of the world though!  In fact, i bet we can diagnose, and fix you're problem easy!

So, how 'bout it?  Pop some new batteries in there, turn the volume all the way up, and let's get started!

1) Does your Gameboy's Power Indicator light up?
If yes, go to 4 | If no, go to 2

2) Are you sure those are new batteries?
If yes, go to 3 | If no, Get new batteries!!

3) Are the Battery Contacts Clean?
If yes, Read Section I | If no, Clean Them!!

4) Turn the contrast knob all the way up, and then bring it down slowly- does it look like the gif?
If yes, go to 5 | If no, go to 8

5) Are their lines in the screen when turned on highest contrast- as illustrated in pictures 1 and 2?
If yes, Read Section II | If no, go to 6

6) Did you hear a chime after boot?
If yes, Read Section V | If no, go to 7

7) Plug headphones into the headphone port, and restart- Do you hear the chime now?
If yes, Read Section III | If no, Read Section IV

8) Does the gameboy atleast go from a brighter screen to a darker one?
If yes, go to 5 | If no, go to 9

9) Are there two horizontal lines fizzing in and out on the screen?
If yes, Read Section VI | If No, Go to 2


Section I
Seems like you have a problem with your Gameboy's Power Supply- maybe it's the regulator?  My suggestion is to open it up, and see if you can find a blown capacitor, or other signs of damage!  Don't worry, your Gameboy isn't scrap yet!

Section II
Lines in the screen, both horizontal and vertical are pretty common- don't sweat it, you can fix these easy!  Once you have your Gameboy open, check out the screen- you'll notice the contact pads directly below, and to the right of it.  Run your soldering gun over very quickly until the line disappears!  Just be sure not to burn though the insulation!

Section III
Most likely a problem with your speaker- it's not really all that uncommon, often they'll get junk stuck inside of them and whatnot.. Don't sweat it though, we can replace it, or just remove it!

Section IV
Sounds like a classic audio problem- maybe you're preamp blew a cap?  Once we open it up, look for visible damage!  You're Gameboy can be saved!

Section V
You seemed to have booted fine!  What are you doing here?! :p

Section VI
Seems like your Gameboy's clock is messed up, no biggie, we can replace it!


Problem Fixed?  If not, please let me know!  We'll figure out what's wrong!

Step 3: Hopes, Dreams, Colors, and a Small Taste of Everything Else.

Before you can get crackin' opening up your DMG, now's about a good time to start thinking ahead/figure out what it is exactly you want in your GameBoy.  Interested in controlling the speed/pitch of your GameBoy?  Or maybe MIDI support would tickle your fancy?  Maybe you just want some sweet LEDs to complement your clear case?  And of course you can't forget about painting it! (while not the most important, everyone knows a cool looking Gameboy plays, and sounds better than a bland one!)  
Whatever the case, make sure you have a plan before you start building.

Below i've compiled a list of popular mods, given an idea of how much space each'll take, and have linked some awesome examples of each, see what you like, and when you have a feel for what each does, and what you want, it's time to start designing!

Backlight - One of the most important mods for long term music writing, Backlights in DMGs, Pockets, and even GBCs have come a long way since they first originated.  With a relatively simple install, and next to no space taken, a Backlight is a must have- especially when there's tons of colors to choose from!

Prosound - Probably the most common and easiest of mods for the DMG, Pocket, and Color, the Prosound mod helps fight gain by catching the audio before it runs though the pre-amp.  This mod fits many places, as it only requires and audio jack, and a tad bit of rewiring.  Stereo and RCA jacks are most commonly used, but when trying to conserve space, the stereo jack already wired into the gameboy can be rewired to be 'Prosound.'

Under Clock/Over Clock - A bit more simple of an install, over, or under, clocking the gameboy allows you to change the speed at which it runs- but unlike the pitch mod, the clock speed we choose will not be variable.  You can use just about any ol' crystal for this, and wiring in a switch, to switch between speeds, is possible!  This guy won't take up much space, and is a great star if you're a bit worried about the circuitry that goes into the Pitch Mod!  (because this is mostly internal there's no picture)

Pitch Mod - One of the most neat mods, this little guy works by cutting off the crystal oscillator that normally controls your GameBoy's speed, and replaces it with a signal from a LTC1799 that varies with the voltage supplied from a potentiometer- ergo, you can control the time your Gameboy runs at, therefore controlling the pitch (think over/under-clocking).  Although the LTC is nice and tiny, the pot can get pretty big, and although it's common practice to remove the speaker and use that space for the pot, i like the idea of using a slide potentiometer on the side.  If you want to be able to enable/disable to Pitch Mod, like in the video, plan on leaving room for a switch!

Biversion/inversion- A huge help in the field of contrast, and an awesome looking mod to boot, Biverting a gameboy give you the option to switch between an inverted screen, and a normal screen by- you guessed it- inverting bits of data before they reach the screen!  A pretty simple mod, only requiring one chip, this is sure to spice up any DMG!

Internal LEDs - Nothing goes better with a clear cased gameboy than some sweet LEDs!  A super simple mod, not much space will be needed for this one!  (account for a switch if you plan to add on though!)

PS/2 Keyboard - A nice simple mod, with a couple of options: Either connected though the link port, or using an internal PS/2 jack- this mod is a perfect fit for anyone playing live.

Arduinoboy - One of the most interesting mods, the Arduinoboy will give your Gameboy full MIDI in, and MIDI out support!  The Arduinoboy also brings with it an array of LEDs that will flash along to your tunes!  Although originally designed for external use, many modders have made use of the Arduino Mini/ Mini Pro to create an internal Arduinoboy!  Taking up quite a bit of space, an internal Arduinoboy has a couple variations, and will be a challenging build for anyone new to electronics!

The pictures above show the space you'll have inside, as well as some common placements of parts inside a DMG!  Also attached is a template that can be either printed, or opened in an editor so you can create a hard/soft copy of your design!

While designing, it may seem tempting to plan to add ALL THE MODS, please do keep in mind, the space you have to deal with is very minimal!  Granted you shouldn't let this limit yourself, but if this is your first build it may not be the worst idea to start small. (refer to last picture above, of my first build)

Part's List Note:
The majority of Parts Lists link to a specific product on eBay- this is because local shops, like Radioshack, don't carry some of the more exotic parts!  A simple search of the part's title will yield you many more places to buy though- if you prefer to deal off of eBay! Link parts are also not the only parts that will work!  Don't let them limit your creativity!

//Although not ready to release, i'm working on a DMG designer flash app!  It'll let you design your GameBoy- accounting for space and everything!  When/If finished, i'll post it up here for use!//

Step 4: Dismantling

Alright!  Finally to the good stuff!  

Taking apart a Gameboy is pretty simple- just a couple of screws to undo, a ribbon cable to (carefully) pull, and a speaker to wiggle out!

Depending on your model, you may or may not need a Tri-Wing Screwdriver, for the back screws.  A Tri-Wing Screwdriver has a tip that looks like a Y, rather than the Phillip's +, you can find a good quality/cheap one- here!

Once the back screws are out, you should be able to pull the two sides of your Gameboy apart- but be careful!  Holding the two together is a little ribbon cable you'll have to disconnect.  To do so, just pull strait down from the connector, as shown in the gif!

Once the two sides are separated, unscrew the remaining screws (locations shown above) on either side, once done, you should be able to separate circuit from casing!

Now just unscrew the metal backing that lays where the cartages go in, and...

Congrats!  You've fully disassembled your Gameboy!  Remember to hold on your screws, we'll need them later!

Step 5: Cleaning & Painting

Having painted quite a few DMGs, i've learned a lot about ruining them!  Hopefully i'll save you that trouble!

First thing's first, deciding how you're going to paint it.  

I've tried spray paint, but i've never had much luck- although you can achieve really cool results, i tend to stick with an airbrush. You could get away with a lot honestly, just make sure the paint you're using is oil based, and made for plastics!

Countspicy also mentioned using vinyl dye, which can be found at most local auto stores- although i've never tried myself, i'll try to get my hands one some- and hopefully post the results!

There's not much too much else to go over here, but i do have a few suggestions!  Hopefully these'll help you in your travels!

- Before painting, make sure to have removed all stickers, the metal sheet (to hold in games) on the back, and the battery contacts in the DMG- check the gif for a super simple way to pop these guys out!

- It's not a bad idea to scrub down or soak your DMG before painting- a Magic Eraser works wonders!  Otherwise just a nice rinse in water/soap should do the job!

- Depending on the look you're going for, sanding may be a good route to remove dents and nicks!

- Many Chiptuners complain that painter's tape doesn't hold tight when spray painting, i have found that Frog Tape seems to work just fine though!

- Battery contacts rusty, or covered in acid?  Try soaking them in a 70/30 mix of water/vinegar!  If they're still not clean, think about using super fine sandpaper to sand off those imperfections!


Comment you're own suggestions and tips!  I'd love to hear from ya!

Step 6: A Bright Begining: the Backlight

Sorry to interupt, but Gameboy Color folks- you're going to have to do this entirely differently! Check out Zachariah Cruse'sInstructable here!

You DMG and Pocket peeps keep reading!

Super popular among the DMG chiptune community, there's a good chance just about every modded Gameboy will have some sort of backlight!  With many different kinds, and colors to choose from, it'll take you much longer to pick one, than it will to install!  As of now,
ASM corners the market when it comes to DMG backlights, and you can learn more about them/see them in action, on his page here!

But before we go on, let's talk a little about how one of these bad boys will work.  The average DMG backlight is really only composed of a few parts: 3 or 4 LEDs, a resistor, the plexiglass dispersion sheet, and some films above and below it- which simply bend the light, making the most out of the LEDs at the bottom.  

We're not going to have to deal with any of that though!

ASM backlights are super easy to install, and although i'm only going to be going though how to do it on a DMG, it's very possible to do this on a Pocket as well.

Parts List:

Gameboy Backlight!
Switch*

*Optional

Start off by taking a look at the board containing your screen.  We're going to have to peal off the black rubber piece on top of the contracts- this is normally here to help defend against blank lines in the screen, so be sure to hold onto it!  After that, start unscrewing the two screws holding down the ribbon cable, once those are gone, we're good to peal back the screen!

Now comes the tricky part; grab a knife, razor bade, or very sharp object of sorts, and wedge it between the glass the backing of the screen.  Keep applying pressure, and eventually it'll start to peel!  Take it slow from here!  Otherwise you'll end up leaving behind foil.

I pulled mine up a bit too fast to show you what will happen, and as you can see the adhesive back came off, but it left a good amount of foil.  If this does happen to you, don't worry!  Just scrape it off!  Nice a gentle to avoid scratching the screen.  

Once we've got the old backing off, we're good to toss in the Backlight!  Depending on your model, your polarization screen may or may not be attached to the screen.  In my case, it was a separate piece* so i slid in the backlight- wires going down, and then put the filter on top- facing in so that my screen would remain un-inverted.
*You're able to invert your screen by turning the polarization screen 90°- More on that in step ***!

Now we can lay the assembly back down, and put back on our rubber piece. In my case, you can see my screen needs a bit of cleaning- a touch of Goo-Gone, and a little elbow grease will fix that!

Once we've done that it's time to solder in our screen.  Although you could really use any +5v/ground points, the closest are going to be from the capacitor right below the ribbon cable.  Using the diagram solder you're red wire to the left anode of the cap, then finally solder your ground wire to the cathode of the capacitor.

That is, unless you want to add a switch!  To add one, simply take your ground wire, and solder that to one side of the switch.  Next solder a wire to any ground point, and then solder that to the switch.  You should be set!

Finished!?  Great!

Pop you're screen back into the back board, and give it a go!

How's the Backlight?  Wait- it turned on, but you don't see anything?!  Before you freak out, check your screen contrast, if that's not the problem, take a look at your polarization film, are you sure it's in correct?  if still nothing, check your solder points- no doubt you'll have it working by now!

Now that it all works, you're good to screw back in the ribbon cable screws!

And you're done!  If that's all you plan to do, you're free to screw the whole front board back to the front casing- Well done!

Step 7: Getting Your Feet Wet: Prosound

Before we dive in, here's some info on the Prosound mod:
Discovered by Trash80 and brought to life by an eager community of Gameboy enthusiast, what was originally called the 'Line Out Mod' brought a much more vibrant bass and a clean sound out of the average Gameboy by bypassing the it's internal pro-amp.  You know how some audio gets distorted if you play it so though some cheap speakers?  It's the  something is happening here!  By skipping over the amp, sure we may lose some volume, but the sound is so much better.  This 'skipping' is done by taking the lead either directly before, or after it reaches the volume potentiometer and wiring directly to a foreign jack, or to the internal jack of the Gameboy.  

Parts List:

- Wire (22-30AWG recommended, any thin wire will do though!)
- Stereo Jack*

*May not be needed if you plan on using the internal jack

(Of course you'll also need a Soldering Iron/Solder, but i'm assuming you already know that)

Now, you have noticed i mentioned there were a few different ways of wiring this, and we'll talk them over in just a sec, but first, let's take a look at our board (you'll be wanting to look at the back board for this).  Use the first image as a reference to the five leads of the volume pot. 

From here we have two options- do we want to take the audio after it's processed though the pot?  Or do we want the raw sound?  In all honestly, unless you're planning to route the audio though something else (you're own amp, for example) there's really no reason to take it before the pot.  Using the 'Post' method also allows you to raise/lower the volume with the pot- as you would using the built in audio jack!  

Make sure to remove the batteries before you start soldering!
(if you forget, it's not the end of the world, just one of those safety things!)

From there it's just a matter of soldering the three wires, and latching them onto your new jack!  Below are diagrams/pin outs for some common stereo jacks, as well as the internal jack.  Remember that if you're using the internal jack, you want to just all other connections from it, refer to the picture to see just what wires you'll need to snip.  (If you don't see the pinout you need, take a look at the diagram showing a standard stereo cable, and use that to help you figure it out!)

Once you're done, toss in some batteries, a game, and plug in your 'phones (you don't need to plug the screen back in)- does it work?!

If so: Awesome! Congrats!

if it's not working, or it sounds grainy, don't worry!  Just check your connections!  It maybe that you have some cold joints, just touch it up a bit, try holding you soldering gun on the contracts longer, creating a better joint, and check again!

Step 8: Slightly Changing Time: Over/Under-Clocking

Over Clocking has been a common method in the modding community as a way to play games faster- things like Pokémon, and Mother can seem to take for ever to someone who has already beaten the game, and overclocking caught on, as it provided a way for the system to run at a faster speed.

In the Chiptune world, Over and Under Clocking provides a simple way to shift between tones- a Gameboy running at a slower speed will produce lower frequencies of sound, while Over Clocking will make the pitch higher.  But wiring these different crystals to a switch, the user can effectively switch between speeds, altering the sounds to his or her liking!

The Classic DMG and the Pocket run at ~4.2MHz, while the Color runs at ~8.4MHz
The above is important to know when we're picking out new crystals because not just any oscillator will work- crash speed is at about 3x the normal amount, and with anything lower than 8x we'll start having problems with bit data loss- meaning we must pick out crystals in these ranges:

Classic/Pocket: .525MHz - 12.582912MHz
Color: 1.05MHz - 25.2MHZ
(PLEASE NOTE: The values above are ranges- THESE VALUES ARE NOT TO BE USED!  Only Values between the two!)

But enough jibber-jabber, let's get started!

Parts List:

- Crystal
DMG/POC Half Speed
DMG/POC 2x Speed
Color Half Speed
Color 2x Speed
Switch (2 position)*
               (3 position)*
- Wire

*optional 

Alright, now that we have everything we need, it's time to get started!

*Side note For those of you working on the Gameboy color, below is very similar, but for better pictures check out this awesome instructable by themadhacker!

Start by flipping over the back board of the DMG, and finding the crystal (check the pictures above for help locating it).  From here there are a few different roads to travel, and it all depends on if you're going to want to add a switch back to normal speed or not.  For those of you planning on adding a switch, skip down to 'Switch-able,'-everyone else, check out 'No Switch'

No Switch (Single Crystal)
Just want your one need speed?  Sweet!  In this case you can go ahead and remove the old oscillator- the best way of doing such seems to be with an alligator clip- clip the oscillator, and pull as you heat up one of the legs, then melt the solder on the other leg until you can wiggle it free!

Once removed, depending on the size of your new crystal you may be able to solder it back into the location of the original.  In the event the new on it just a bit too large, solder wires to both holes where the original oscillator once was.  Solder the other sides of those wires to you new crystal, and you're good to go!

You're good to test the bad boy!  If you're having issues, check the joints, make sure all the points of solder are good connections, and try again.  If it's still not working, you may have damaged the crystal- the chances of this are low though, so i'd check your connections again!

Better? Awesome!  You're doing great!  Onto the next mod!


Switch-able (Multiple Crystals)

Too cool for just one crystal?  I feel ya!

First you need to make sure that you have a switch that'll work.  For have two separate crystals you'll need a two position switch- for three you'll need a three position switch, etc.

For all intents and purposes the diagrams above will not just how to wire two crystals, but also a three crystal setup!

Following the circuit diagram, you should have no trouble wiring this all up!  Basically you're going to wire one side of all the oscillators together leading to one of the original oscillator holes, while the legs on the other side of each oscillator will be soldered to the switch.  What this will be doing is using the switch be be determine which oscillator will receive power (this power coming from one of the original oscillator holes), while their outputs are filed into the other oscillator hole!  I'm over complicating it, just look at the diagrams...

Now that you've got it all hooked up, test it out!  If it doesn't work right away, its alright!  Check you're connections, and if they look good, make sure you have it wired right.  If both check out- double check!  You'll find the mistake!

Once you do, and you're golden!  Enjoy your multiple 'clocks!'

Step 9: Controlling Time: the 'Pitch Mod!'

Just some quick background on the mod:
The Pitch Mod got it's big break over at Get Lo-Fi, where a kit and instructions were posted almost 4 years ago!  Of course since then the mod has undergone some slight improvements, but the basic design remains the same.  Based around the all mighty LTC1799, a precision oscillator, the mod aims to provide a slightly higher, or lower clock frequency making the Gameboy run faster or slower, respectively.  Using a simple circuit the LTC can produce waves from anywhere from 1kHz to 33MHz, and with an added pot we can scan though that range, allowing pin point speed!  As mentioned earlier though, the LTC is super tiny!  As it's only in an SMD package, and only about 4mm long, break out your magnifying glass, and let's get started!

Parts List:
- LTC1799*
-
 SOT-23 6 PIN to DIP adaptor*
- Break-Away Male Headers
- 10K Resistor
-
 100nf Capacitor (marked 101/104)
- 500K Potentiometer (or less)
- and of course, Wire!

*The links will lead you to a 5pc set- i recommend this because, i can tell you from experience, there's a good chance you'll ruin the first chip

Alright, after you've acquired all the parts, start by soldering the LTC1799 to the adaptor.  when soldering SMDs the easiest way is use just a tiny bit of sticky tack, or some kind of adhesive, to keep them still.  Then apply just the smallest bit of solder, and drag it away from the chip.  This method, works differently from drag soldering, as we're only going to be soldering to one pin at a time.  For those of you who are new to SMD soldering, like i was, check out this tutorial, it's a huge help!  It's a good idea to check your contacts with a multimeter before you continue- make sure everything's set!

Once the chip and board have met each other, we're going to have to give this adaptor some legs.  In my case, i used left over lead clippings, but a Header of some sort would be much more 'by the book.'

Check the diagram for a bit more clear idea of how the circuit should look, although it should be noted that the third pin of the potentiometer is not grounded in this diagram, as it is in schematic.  Either way will work, grounding it is just a bit more, like mentioned before, 'by the book.'

Once the circuit is completed, it's time to solder it into place!  This will be cake, as long as you pay attention, and solder to the right leads!  Find those leads on the diagram above!  Any +5v/ground spot will work, but the two shown are recommended to save space.

Here you also have to option to add a switch!  Wanna go back to the gameboy's internal clock?  No problem!  just attach a switch between the clock out signal!  If you're not going to ad a switch, it might be a good idea to cut the trace connecting the internal oscillator, which is also pictured.  IF YOU'RE ADDING A SWITCH- DO NOT CUT THIS!!!

Once you're finished connecting everything, reconnect your screen, and give it a try!

Does it work?!

If not- don't fret!  Check all connections first, make sure nothing's loose/shorting.  If everything looks good, check the circuit itself, make sure you've got everything wired as it is in the schematic.  If you still have a faulty circuit, try cutting the trace, and only after that, if you still have no luck, should you go back to the start, and replace the LTC1799.

But if it does work: awesome job!  This one can be tricky to get working on your first try- i'm impressed!

Step 10: Biversion/Inversion

Whether you're looking to make your screen more clear, or just want a cool display, Biverting, or Inverting are both awesome ways of doing so!  As the name implies, in this mod we will use a data inverter to invert the signal coming to our screen!  Although i'll cover their operation, you can find more info on how these chips/ the Gameboy's screen work here, on nitro2k01's page!

Now before we jump in, it's important to know the difference between Biversion, and Inversion.  

Inversion will reverse the color scheme making black: white, light grey: dark grey, etc..  This will be permeant though, and you will not be able to switch back to the normal scheme without changing around you Gameboy's circuitry.
Inversion can also be obtained by rotating the polarization film on your backlight 90°*

Biversion simply enables the ability to switch between an inverted and un-inverted screen.

*This polarization inversion is sometimes used with a chip inverting the display once more, creating a more clear original color scheme.

Now that we know what's what, decide on which mod you want, and scroll on down to the directions!

Biversion

Parts List:
74hc86 (I'll be using a DIP package so it's easier to show, but i recommend a SMD)
SOIC14 to DIP Adaptor*
Oh, and Wire!

*Only necessary if you're buying a SMD package

Let's start off by checking out where we're going to be operating in this mod.  Once you've found the post right above the screen ribbon cable jack, slice the two traces shown in the picture!  Make sure to cut below the via, and to make sure you don't accidentally cut anything else.  Once those contacts are history, we're going to start soldering wires to the chip!

As we're going to be Biverting, take a look at the 74hc86 diagram, and attach wires the legs as necessary.  

The 74hc86 is made up of four XOR gates: we'll be using only two of them though.  If signal goes into both inputs of the XOR gate, the output will come out negative, while if only one is powered it'll turn out a positive.  This means if we power one of the inputs (this is what the PWRs are doing) we will invert the signal coming from the board!  the Biverting comes if we 'short' these PWRs to ground- which is what the switch will be doing!  Finally by wiring the output directly to the screen's jack, we will be able to bivert the screen!

Now that we know how it works, it's time to hook it up!  Wire the chip to the correct spots on the board, as shown in the diagrams below, and you'll be set!  (Check the later diagram for Vcc, and GND sources!)

If you're having trouble wiring to the jack itself, try sneaking the wire around the back- checkout the last diagram for help on this- it can be though!

If you're having issues, make sure nothing's touching, use a continuity meter if you have one- if you're sure nothing's touching, yet the mod still won't work, make sure you wired the chip correct- and that you used a resistor for the incoming signals!  If you forgot the resistor, you may have blown the chip, meaning you're going to have to replace it :(

If it does work though, nice job!


Inversion

Parts List:
74hc04 (SMD package recommended!)
SOIC14 to DIP Adaptor*
As Always, Wire!

*Only needed if you're using an SMD Chip

Once you've got the parts, lets checkout where this is all going to go down!  Just a bit above the screen's ribbon cable jack, we're going six joins forming a rectangle.  From here, we're going to cut two traces that make their way to the jack itself- see the pictures for a better understanding.

Before we go on, let's take a look at our chip!  The 74hc04 works on a similar principle as the 74hc86, but rather than having two inputs,  it already has one leg powered- in lamen's terms, input goes in, inverted output goes out.  

With that under our belts, we can solder it up, just like in the diagram!  

Now we're set to solder to the board!  Follow the pictures, the bits come from the comb of six points, and the bits out should be wired directly to the screen.  This part can be tricky, as the screen jack really doesn't like being soldered to- and accidental bridges happen just a bit too often.  If this sounds like you, try bending you're wire, and scooping it underneath the jack's legs, it's so much easier to solder as so!

You're good to test after that!  Plug in your screen, and give it a go!

How's it work?  If you're screen is blank, or all black, it could be because you have touching contacts.  Make sure you have clean joints, and try again, no doubt you'll get it!


Step 11: LEDs (Internal, and Beyond!)

Nothing beats a sweet set of LEDs lighting up from within your case- or maybe you're interested in changing out that nasty red power indicator?  No matter your intentions, this step is for you!

First, lets take a look at adding LEDs within the case- an awesome way to make your Clearboy even cooler!

Word of warning though, the original Gameboy and Pocket share many +5v sources, but if you're looking to work with the color i suggest checking out this instructable by 1Up!

Parts List:

LEDs! (Kind, color, and size are all up to you!)
Wire!

How we go about this is really up to you!  

I personally like to defuse my LEDs- by just sanding off a bit of the epoxy, you can ruin the focal point, giving it a much more even glow! 

Depending on the LEDs you're using, you may need to toss in a resistor, check out this LED Calculator to see if that's the case!

Once you know that, it's pretty simple!  There's tons of five volt sources, and probably even more grounds!  All you need to do is pick one of each, and solder your LED(s) to it!

Look above for a pretty simple example.

*If you plan on wiring more than one led, i recommend soldering them in parallel, that way you don't have a noticeable drop in brightness!  You'll find this draws A LOT of power from the gameboy though- so, using anymore than two LEDs may require a power source other than the gameboy- in my case, i have 3 button cells tucked away to power these!*

If you're LED doesn't disperse enough even when defused, hot glue works well in spreading the light!  Sort of like the Backlight, and it's film with the holes!  Although it may look hideous from the inside, it looks great put back together!

For those of you looking to replace your power indicator, You're going to have an even easier time!

Parts List:

LED (3mm)

First we're going to need to remove the original power LED, this is easiest by clamping with either pliers or an alligator clip, and pulling it as you melt the solder on the back.  Alternate between the anode and cathode side until the LED pops lose!

Once that's out of the way, thread the new LED in, longer leg facing up**.  Slide it though, and use the solder already there to keep it in place!  

Power the Gameboy up, and give it a go!  If you're having problems, check your solder job, sometimes the older solder likes to give itself cold joints- make sure that's not your case!

Now that it's working, you're set to show off your bright new Gameboy!

**More pics on the way!!**

Step 12: PS/2 Keyboard

Credit for the PS/2 Keyboard goes strait to the LSDJ team, a development that came along with the program in an update, the option for a keyboard brings a whole new dimension to jamming out live!  

A Simple set up, we've got two ways to go about this: 

1) We could splice the Keyboard's wire, and a DMG Link Cable together, meaning you could plug the keyboard in and out of the DMG- bypassing all PS/2 elements, or...

2) You could create an interneral/external PS/2 jack, which you could plug and unplug any PS/2 keyboard from!

Both styles have their pros and cons, so take your pick, and scroll to that step below!

Splicing 

Ready to slide and dice these two cables into a truly awesome, LSDJ playing, Piano? Let's take a look at the parts, shall we?

Parts List:

- PS/2 Keyboard
-
 DMG-07 Link Cable
- Electrical Tape/Heat Shrink Tubing

Alright, there's no easy way to say this, but you're going to have to cut open your cables now :c

Snip the Link Cable as close to the center as possible (this way you have another 'Half-Link-Cable' you can use for another keyboard or another project!).  Now cut your keyboard! (placement doesn't matter so much here think- how long do you want it to be?)

Now take a look at the Link Cable, peel away some of the black wire casing to get a look at the wires within!  Hopefully you'll have five- a blue, a red, a green, an orange, and a yellow (this isn't counting the messy ground/shield that has no insulation).  If you're unlucky like me, and only have the four- we're going to need a different power source for your keyboard- perhaps some batteries?

For those of you with the correct five wires, check the diagrams from this ChipMusic thread (also above) for some common keyboard wiring colors- if your PS/2 keyboard doesn't match one of these, you're going to have to test a few different combinations.

Now just join the wires together, twist them into each other, and maybe add a little solder to hold on better, and WA-LA! you're ready to test!

For those of you without the yellow wire (like me) you're going to have to connect the wires you can, but for where the yellow DMG cable is, we're going to substitute as power source!  I recommend a CMOS Battery for their size, they're small enough you could even fit it within the keyboard itself!  You're going to want about 3-5volts to power the keyboard.  Just connect the hot lead to the appropriate  wire, and the other battery point to ground!

Give the Keyboard a go before taping/heat shrink tubing the wires shut.

Remember that  LSDJ needs to be set to special settings- XERO does a great job of covering the software side of this project here!

Give it a go, and if you're having problems, i strongly encourage you to take a look at your settings in LSDJ before tearing about your wiring.  Only when you're positive it's not software-related should you try switching out wires!  Just be patient, and keep trying! You'll get it working!

Internal/External Port

Parts List:


- PS/2 Keyboard
- PS/2 port (your best bet is to buy one like this, a cut it in half, tossing the USB end)
- DMG Link Cable
- Wire

First step for an internal port is going to be finding where the link cable is soldered to the board- check the gif if you need!  From here we're going to have to solder some wire onto four of these bad boys.  Look at the the PS/2 diagram i whipped up to see just what four wires you'll need.  When soldering to these joints, you most likely won't need to add any solder/flux, as already these points are overflowing with both!  Make sure you've got not bridges, and all wires are secure!

Alternately, if you want your jack not in the gameboy, you can attach it to the Link Cable itself, just follow the following directions!

Now that we've got wires from the Link Port, we're just going to need to wire those to the PS/2 Port!  Use the diagram once more to see the positions each needs to be attached to!

Once you've got everything in place, make sure to test it before you close up!  If you're having problems, make sure you have your LSDJ settings correct, this can be even more tricky than soldering the port!  XERO does a great job of covering the software side of this project here!


N
ow that you've got your keyboard setup, check out the last picture above to see just exactly your keyboard can do!

Step 13: Arduinoboy

This is it guys.  The big one, The Ardunoboy.

Created by Trash80 (who you may remember from the Prosound mod), the Arduinoboy was designed as an easy way to integrate MIDI control to DMG, Pockets, and Colors everywhere!  Since it's creation there have been many different styles, some of which are even internal!  Here you'll find the 'Low-Down' on all of them, and hopefuly put one together yourself!

Although the All in One Graphic (prepared by Trash80 himself) above tells you just about everything you need, lets break it down a little, get to know it better, and get building!

So..

Parts List:

- Arduno! (Uno is recomended- Pro Mini if you plan to go internal!)
- 6N138 Optocoupler
- 1N914 Diode
- 220 Resistors x2
- 270 Resistor
- 2K Resistors x7
- Push Button (any momentary push will work!)
- DMG Link Cable*
- PCB/Perf Board

*Internal Mounts will not require this!

Now that we have our parts, it's simply a matter of following the diagram!  I personally like to chunk it up, give myself a few parts rather an a large one!

Start by creating the Optocoupler's circuit- solder in the chip, followed by the diode, then the two resistors, then attach wires were necessary, to link to both the MIDI port, and back to the Arduino.  One down!

Now let's start lining up all the other resistors, here you can see i soldered seven in a row- six of which will be used for the LEDs, the other for the push button.  One their lined up, solder on some wires, attach you're LEDs, solder to the Arduinoonce more, and you're set!  Part two down!

Now lets wire up the MIDI out- just a simple resistor, and some play on the Arduino!  Well done- we're almost finished!

Finally we'll attach this all to either out DMG, or our Link Cable, either way, i created diagrams for both!  They're a little more clear than the main one, so make sure to take a peak!

Now that we've set it all up- why not give it a go!  Download mGB, and flash it to a cart- plug it into your Gameboy, and Jam out!

If you're having issues don't fret!  Just check you're wiring!  Double check you've got no cross talk, or shorts!  Also check you've got the latest version of mGB, and that it's working proper!  All in all though, Arduinoboy issues can be specific, so please, if you're having problems, comment them below!  You may just be helping someone else, with the same problem, out!

Step 14: A Quick Chat About Software

You may have the coolest DMG on the block- but that doesn't mean anything if you don't have the proper software to make music on! And so that brings us to one of the final chapters of this Instructable, Software.

But what is Software without a way to play it?  That's right, we're going to need a Flash Cart.

You've got a few choices, so i'll break them down for ya,

USB 64m Smart Card - A perfect place to start, the Smart Card is the perfect balance between price and user-friendly-ness!  Using a USB interface to connect to your computer, the Smart Card has two separate menus meaning you can store LSDJ on one, and tons of other games/software on the other!  As the name implies, each side holds 32m of data, meaning you have plenty of room for plenty of ROMs!  The only downside is that you can only have one Save File at a time, which isn't too big a deal if you're careful!  Burning ROMs/backing up Save Files requires additional drivers, but these are easily obtainable on Kitch's website for free!

Drag 'n' Derp - Although a bit more pricy, the Drag 'n' Derp takes all the drivers out of the burring/backing up process!  Literally just plug in the USB, and drag!  The Drag 'n' Derp is perfect for beginners who don't want to both with tricky programming!  Laking a second menu- the Drag 'n' Derp will only let you hold one ROM at a time,a only has 24Mbs of space.  Check out Professor Abrasive's Website here for more info!

Bleep Boop - No longer for sale, you may still find an old one floating around online.  Bleep Boop cartridges are known for their flashing along to your tunes!  With many different models out there, it's tough to give out specs!

Nanoloop one - A cartridge made solely for the program Nanoloop, no programming, or case necessary- if that's all you want!  The cart allows one to program up to two other 32k ROMs though the use of a Link Cable to USB adaptor (for sale on Nanoloop's site!) Of course you can also use this adaptor to update Nanoloop!

Gameboy Camera - Nintendo's Gameboy Camera has a DJ mode, which is simple and fun to use!  Not to mention the carts are relitively easy to come by!  Plus, it's a camera for your Gameboy!!  That in itself is enough for me to want one!  (Thank you to WacoRadioWeirdo for reminding me of it's feature!)

Each of these carts work with any Gameboys- but can only hold roms from the GBC, and DMG


Okay, cool!  Now we can finally talk about Software!  After all, i think that's what this step was all about right?

So what are our options?

LSDJ - Number one for pretty much every Gameboy musician, LSDJ is an awesome little ROM that you can pick up for a donation of your choice!  With so many options and features- i'm honestly not sure i can sum it all up in just a paragraph!  Control all four channels of your DMG, utilizing tons of built in samples (Phonemes (speech) and all!), and tons of different pre-programed features like envelopes, and stero/mono control- oh gosh, i'm getting worked up just typing this!  Seriously though, check out the page- and pick up a copy of the ROM!

mGB - Once again we see Trash80's brilliance, in this nifty program designed not so much for making music on, but rather to control your Gameboy though MIDI with the use of an Arduinoboy (see step 13)!  Easily flash-able to any of the first three cartages, be sure to download the latest version if you plan on building an Arduinoboy!

Nanoloop - Much like LSDJ, Nanoloop is another way to create your jams- but unlike LSDJ Nanoloop's more simplistic style of pressing buttons to add to your pattern, negates the long time spent programing a song in LSDJ.  Although commonly found on Nanoloop One carts, the ROM can be downloaded and burnt to just about any cart!

Shitwave - Excuse my fowl langue, but nitro2k01's typo while creating his program 'Shiftwave' is easily overlooked once you see what it can do!  Creating a sweet glitchy sound by cycling though all 16^32 possible wave frames on the DMG in a random fashion! Give the Program a look if you're interested- clocking in at just over 300 bits, i'm sure you'll be able to make room for this one!

Coolio Tutorials!
Below will be some sweet tutorials for LSDJ- there's a bit of a learning curve, so it may not be the worst idea!
D&D Sluggers

Of course there are tons of other programs out there, but these are the basics!  Think i've missed one?  Comment below!  I'd love to learn about more!

Step 15: Close Up & Closing Remarks

Now that we've got your Gameboy totally maxed out on mods- it's time to cram everything inside, and screw it all back together...  It's kinda sad in a way- At least until you turn it back over and see the sweet instrument you've made!

I hope both you, and your game console of yesteryear have come far since the start of this Instructable!  Thanks for putting up with my silly diction, and overuse of comas!

Feel free to show off your builds in the comments below- i'd love to see what you guys have come up with!

And please, if you've enjoyed the tutorials, Please consider voting for it as a winner in the Music Instruments Contest!  It'd mean the world to me, and it's only a simple click!

Thanks Again!  See you next build!
I like this tutorial a lot, it's very informative. However, it's so info-dense I don't know where to start. It's very unclear what I actually NEED to make music, and what is just other cool stuff to do. I'd like to know what is the easiest and most bare-bones way to make chiptunes on a DMG?
Also, I am super dumb and while I'm sure this tutorial makes perfect sense to someone smarter than I am, I would LOVE you if you could make a 'talk to me like I'm five' version.
<p>Hello I'm very new to this and I do not understand much of this. I have a GBA SP, what will I need for any of this because all I see is the usage of a GBC. Please help me I really like chiptune and I want to try other ways to make this music.</p>
Hello, what you see here isn't even for GBC, but for the one before, the one that started all, the DMG (Dot Matrix Gameboy).<br><br>Whatever, I'm afraid you can not do anything following this tutorial, the GBA SP is using veeery different components than it's oldest brother.<br><br>But tell us what do you want to mod on your SP, maybe we can help!
I'm with Wdash, none of this makes any sense to me. I'm too dumb w circuits and none of the equipment links work anymore so I don't even know what I'm supposed to buy anymore in order to follow this guide. Fml
<p>Haha, sorry about the links! I'm just now realizing Radio-Shack no longer hosts many of their parts online (Nor in stores RIP RadioShack)<br><br>However, even without silly parts I picked, you can TOTALLY do this!!<br><br>You don't pick this all up over night! It takes time to really understand what you're working with!<br><br>However, no one is &quot;too dumb&quot; to work with circuits! You can learn anything with some research! There are <em>soooooo</em> many great places online to learn, I don't even know where to begin!<br><br>If you have any direct questions, or points of confusion, I'll do my best to answer them though!</p>
I finally watched a backlight installation in real-time to understand exactly what I'm supposed to do. Will be doing that first (: might get confused again on the prosound jack but I'll cone back to you on that, thanks!
<p>See... I knew ya could do it! Just takes some research!</p>
<p>I've seen other tutorials in which they use the original internal jack.<br> <br>What's the difference between this and placing an external (new) one? Less noise and humm, maybe? Also, do post or pre do anything to the sound quality? My guess would be &quot;no&quot;...</p>
<p>No difference. It's just harder to accidentally pull out and RCA or 1/4&quot; plug than an 1/8&quot; headphone style one.</p>
<p>:)</p>
<p>Pretty late to this reply, but Toastalicious is right! No real difference between the two!<br><br>Those who use the internal jack generally disconnect it entirely from the board, and just rewire it (as described in the instructable) Doing it this way can make the internal jack sound just like something new! (This process would indeed involve cutting all four wires if you cut the speak out as well! Otherwise cut only the right two most of the cables running to the internal jack (these are right/left audio-- replace with 'pro-sound' connections) to use the plugging of headphones in to toggle the speaker on/off)<br><br>Pre/post-pot connections are a little different-- you'll get a little more <em>buzz</em> with the post-pot conections, however this will also let you use the volume knob. Wiring to pre-pot will give you a tiny-bit more clear sound, however the difference isn't worth losing that lovely volume control.<br><br>This is a bit rushed, so I apologize if my explanations aren't 100% clear. Feel free to ask anything else you may be having troubles with!!</p>
<p>What about cutting all four wires and even getting rid of the speaker?</p>
This instructable doesn't really make any sense to me.... I guess I'm too dumb :(
<p>Aww.. Don't say that!</p><p>New project always confuse me in the begining! But once you dive in, everything becomes more clear..</p><p>What's trippin' ya up? Maybe I can clear it up!</p>
Aww, don't say that!!<br><br>New stuffs like this is always confusing at first! I've always found once you dive in, things start to become more clear!<br><br>What's confusin' ya? I'll do my best to help!

<p>Hi! One question: i really CAN'T REMOVE the gbc crystal oscillator....please, help me! </p>
<p>hi, i have a question \. My gameboy color's power light turns on and the screen goes black, it makes the little shiny sound when started but wont respond to buttons or any game hat I put on it. any suggestions?</p>
<p>I have 2 3mm green and 2 3mm blue leds with 82ohm resistors wired to the positives and they're ran in parallel. I also have a 4xLED white backlight installed, and the leds are hooked to a dpdt switch. that worked great so far.. but then I added a variable pitch mod and now I hear sound, but the screen is blank and it's not responding to button presses.. what's wrong? wire touching something perhaps? oh, and the leds are connected to a potentiometer(A20K) and so are the LEDs on the other side of the dpdt switch(but I connected the on/on's to eachother so the leds will stay on and the switch is for the variable mostly)</p>
<p>While doing the backlight, I was peeling the foil, but a lot of foil got stuck on the screen and only the adhesive part came off.. Is there any way to remove the foil without scraping it?<br>Thanks for the tuto!</p>
<p>Well I got another DMG and everything came off easily! I guess the other one is on stand by.<br><br>One more question, I want to put RCA &amp; TRS Prosound. I do the RCA connections on the mid-right back part of the DMG and the TRS on the bottom part?</p>
<p>One more question, is there any problem if i remove this part? (RED SQUARE)<br>I want to put a 1/8 female TRS panel and this space empty will be usefull.</p>
<p>Sorry, i meant 1/4 TRS female panel</p>
<p>what is the difference between using internal jack mode or the 1/8 outputs for pro sound mod?<br>and thanks for that great tutorial <br></p>
<p>Hey! Sorry for the late reply! I guess I stopped getting email notifications for comments..? Anywho......<br><br>There's no real difference between putting in your own 1/8&quot; jack, or using the original port.. Some people prefer to keep the original intact, so they can always hear that nice OG gain, but if that's not what you're looking for, wiring up prosound to that port can make the DMG look a lot more clean!<br><br>As always, it's all a matter of preference!<br><br>Hope this helps,</p>
<p>i juat got this im new to it all any tips in how to use slash improve is a gba better then a normal gb to use. i have a itch to make beats</p>
Well it looks like you've gotten a great start!!<br><br>Mod wise, I've seen backlights, prosound, even a few pitchmods for GBAs, but for how to do them..? You're going to have to check wit hthe pros!<br><br>This guys has some awesome looking GBAs: https://rosecoloredgaming.wordpress.com/ I'd check there if you're looking for inspiration!<br><br>Happy Chipping!
<p>You should compile this tutorial into an eBook- I would totally buy it.</p>
Wow, I've never thought about that!<br>If it ever come to fruition, expect a free copy :p
<p>Hey, I backlit my DMG, but now when I try to load certain cartridges the screen is just blank. Any thoughts on what's causing this?</p>
Uh oh!<br><br>There's a few reasons this could be going down- I'll need some more info to be able to tell for sure..<br><br>What kind of backilight? Did it have a built in resistor? Did you put on in if not?<br><br>What ground/+5v line did you use?<br><br>You can see the Nintendo start up splash right? If so, It sounds to me like your screen is just using up too much power, and when the gameboy goes to load whatever game, it browns out.. (do you notice the screen getting more dim when this happens?)<br><br>Hopefully we'll get to the bottom of this!
<p> I used a backlight kit I got from handheld legend. It works great, I'm just having a few minor issues with it. All my carts work, including the one I use for LSDJ, which is good. The main cart I'm having issue with is pokemon red. When the gameboy starts up it works fine except the nintendo logo doesn't appear and I don't hear the bell start up sound. The gameboy and backlight both start up but nothing appears on the screen. I don't think there's anything wrong with the cart since I've tried it with my gamecube GB player and it works fine, it just doesn't work with my DMG since I added the backlight.</p><p> As for the resistor, I'm not sure. The backlight works perfectly so it would appear that I installed it correctly. Another thing is that with my carts that DO work I'm getting garbled &quot;nintendo&quot; text at start up way more often. I know that isn't a major problem but I think it shows something funky is going on inside the gameboy. </p>
<p>Trouble with a pok&eacute;mon game? Yep. Almost positive that's a power issue! The kit should have come with a 100 ohm resistor to put between the ground cable of the backlight and the ground pin.. Sound familiar? Try this.... Load up a LSDJ save, and hit start. Does the screen dim when the music plays? If so, the backlight's just drawing a bit too much current. It's a common thing, and not normally too big an issue, but pok&eacute;mon games are notorious for their also high power usage..<br><br>Throwing the resistor in should fix any problems with carts! But as for the garbled logo..<br><br>This could mean a few other things... It's most likely also a symptom of low power-- Maybe the clock isn't pulsing just right..?<br><br>I wouldn't worry about it just yet, fixing the power issue will probs fix this too!</p>
<p>how to I go about adding a 1/4&quot; prosound?</p>
Same process as the 1/8&quot; port!<br><br>Be careful the plug isn't mono- or at least if it is, know that you'll want to wire both the right and left sound channels across from the ground wire.. <br><br>You should be able to find a pinout view of your jack though- it'll give you a better idea of which wires go where, because everyone is different!
<p>So can I try LSDJ on an ez flash cart that I have? Also is a GBC just as good as a DMG for chiptunes? I literally only heard about chiptunes because of this instructable, and I think it'd be something fun to try, but not drop a lot of money just to find out I don't like it.</p>
<p>Also, I want to paint my gameboy, then design it using paint pens. What would be the best way of doing this? Should I use vinyl dye or just some spray paint?</p>
If you're going to use paint pens, your best bet is going to be to:<br>0) CLEAN THE GAMEBOY! maybe even sand it down a bit so that the paint sticks well...<br>1) paint the GBC white (or w/e base color)<br>2) use your paint pens to make your designs<br>3) use a clear coat spray paint to 'seal' in the designs<br><br>Step three is crucial, because most paint pens are just acrylic- meaning water can was them off. The clear coat will also smooth out the surface, making it look nice and clean!
<p>Thank you so much! What types of paint would be best? Should I sue vinyl dye or spray paint? Have your gameboys been sticky after paint? I'm planning on painting a gameboy for my fiancees birthday. </p>
Yeah! As long as you can program to the cart, you should be set!<br><br>As for the GBC, the hardware is a little different from the DMG- some say it sounds better! Of course others argue the opposite too.. Either way, it's definitely a great place to start!<br>
<p>For anyone interested I have a couple of builds I've yet to sell!</p><p>Check out my eBay Shop <a href="http://www.ebay.com/usr/ecco3967" rel="nofollow">here!</a></p>
<p>So wait.. I'm wiring two grounds to the switch? That doesn't seem right.</p>
<p>Yep that's it!- well, kinda!<br><br>All the switch is doing is connecting/disconnecting a ground source to the ground wire of the backlight!<br><br>When connected current will flow though the backlight, and when not, the backlight will be off!<br><br>Hope this helps!</p>
Thanks for the response. I need a basic wiring course I think. I just look at some line drawings and it seems to make sense. Excellent tutorial by the way. This is the largest collection of DMG modding I have found in one place. I really appreciate it.
<p>Don't sweat it! My writing is most defiantly rushed- one of these days I'll get around to touching this guy up!</p><p>Happy to help!</p>
<p>Thats amazing! A while back i tried to make some chiptunes with a free software called FamiTracker. This software is great, but is a LOT easier if u have a MIDI controller, so I cant really make a decent song with it. Also it isn't genuine chiptunes. But this ible' is... just awesome. I'm seriously considering buying a game-boy now! P.S. whats whats a &quot;rom&quot; and a &quot;GBC&quot; ? Thank u SO much Ben :)</p>
Thanks for the kind words! So glad you're a fan of the guide!<br><br>ROMs are the digital file that holds a Game Boy game (or NES/64/DS/etc games). most ROMs can be flashed onto a cart, and then played on an original system, otherwise they can be used with an emulator.<br><br>A GBC is just a Game Boy Color.<br><br>Hope this helps!
<p>Hi Ben,</p><p>Just a question, I'm about to embark on modding both my Color and my DMG, but before I begin I wanted to make sure that everything you entailed in this guide applies to both the color as well as the DMG models unless specifically noted?</p><p>Say, if the circuitry in the color is vastly different from the DMG, would that affect the process of attempting any of the mods?</p><p>Also, does it matter the type of solder used when soldering down wires? Is a specific type recommended?</p><p>Thanks very much for the help!</p>
<p>why did you cut the blakc wires ??</p>
