Introduction: Game Boy Bivert/Biversion Mod DIY

Picture of Game Boy Bivert/Biversion Mod DIY

This modification will improve the contrast of your LCD for your original Game Boy DMG. Add a backlight to complete this mod anf illuminate your screen!

Note: Installing this mod without a backlight will invert your screen.



• Tri-wing screwdriver
• Phillis jewelers screw driver
• Bivert Chip (get yours here)
• Optional but suggested back light (get yours here)
• Razor blade
• 28 gauge wire
• Soldering Iron (~40watts)
• Solder
• Helping Hands (if you need it)
• Hot Glue


Step 1:

Picture of

Start by orienting your bivert chip as shown in the photos. Locate and number reach contact. Prepare 6 wires of about 3 inches long. Strip and tin the tips to prepare for soldering. Tinning the wires is a must for this mod, it will make the precise soldering much easier for later.

Now cut two leads on the PCB between numbers 1 and 3, and then numbers 2 and 4. Be careful when cutting. Do not ever any other leads.

Solder the 6 wires to the PCB and prepare to solder them to the bivert chip. Match the numbers as shown in the pictures. This step can be hard to do. Stabilize the chip and use a very small amount of solder. Do not heat the chip too long as this can damage it. Use a small brushing motion as not to connect the tightly spaces pins.

Step 2:

Once you have soldered all the wires correctly, place some hot glue on the chip to keep them for disconnecting. This provides more protection for the fragile connections.

Unscrew the PCB and wrap the wires and chip around to the back to hide it away. Now hot glue the wires connecting to the PCB so that they stay in place. Close up your DMG or continue to mod you LCD with a backlight to complete this mod!

I mucked up a semi-decent installation by putting too much strain on the output pin of the 2nd gate which subsequently caused it to break away. Thankfully, it's a hex inverter so I had 4 more gates to work with. I lifted the pins rather than cutting the traces and used kapton tape to prevent any bridges or shorts. The ribbon nicely covers and protects the IC when fully assembled.

I like the red light color. Helps to keep night vision intact!

What chip did you use?

up-n-atom (author)HarleyS12015-08-18

Same as the 1 sold by HHL. 74HC04D, an SO14 package. It's placed upside down, pin 14 and pin 1 align perfectly with their respected pads. The wire is 30 AWG, solid core. I used flux and solder wick to lift the ribbon pins and slid under the kapton tape. I wasn't satisfied with the spaghetti and went on manufacturing my own PCB.

Smart, nice and clean work! Well done bro'!

"I made it" but failed :(
Screen lacks grey(it's black and white only) and some lines appears when it's on for a minuter or when I push a button. Clearly I made something wrong. Have resoldered the chip and all on PCB.

Here's a video of my mod (it's in swedish). I show the problems right in the end of the video.

Solder skills: 2/5

Not a easy job but finally managed to do it within 2 days(4 hours)

Need to clean the screen though. There is a little adhesive left in the middle of the screen. Got the parts van HHL.

SeanS100 made it! (author)2016-04-02

i made this and the screen only looks good if i am pressing on one of the buttons how do i fix this?

switchie15 (author)SeanS1002016-04-02

very odd, are you using rechargeable batteries?

albpara made it! (author)2016-03-12

Soldering the chip is quite hard and cutting the PCB paths is quite delicate but finally I made it, I have to say that I am not an expert soldering and I need time a patience to solder the wires to the chips.

I strongly recommend to secure your solderig with hot glue after finishing the job because moving the wires broke my soldering a couple of times

switchie15 (author)albpara2016-03-12

There is a new module at that make this mod much much easier.

tevey (author)2015-10-26

I want to make this on my backlight gb pocket is it. But i guess the connections are diffrent. Anyone know how to connect it to a gb pocket?

I followed this tutorial and it ended up with the display missing shades of grey. Turns out that I had accidentally swapped pins 2 and 4. Upon fixing it worked flawlessly!

LeeY5 (author)2015-07-25

I installed the bivert chip which i get from my local store. Wow! It was so bad the image was blur and jumpy. Can't even play. Feel like a tv set with a very bad receiving. What's went wrong? Is the bivert chip sold to me was in correct?

switchie15 (author)LeeY52015-07-26

Make sure to get the right part number. Any old bivert chip isnt compatible.

LeeY5 (author)switchie152015-07-26

Thanks. I will purchase from your store after cleaning bills.

Can anyone help me? Where can i buy polarized film for DMG? Can iphone polarized film as a substitute?

switchie15 (author)LeeY52015-07-19 has them

Do we keep the levels of shading after this dual inversion has been added or does the increase in contrast mean all pixels are either full strength or off?

MrCrono666 (author)2015-04-19

So, I tried this and messed up the first PCB board, accidentally fused two of the board points (3/4) together. Next one I tried I successfully soldered it all together but when turned on, it seemed to be about 60% biverted and the speaker had stopped functioning, will try to upload a picture later on, also will test another chip as I'm pretty sure I might of burned the chip out (or at least damaged it).

Just wanted to talk about my recent experience putting a backlight into my classic gameboy.

I bought a blue backlight from (After reading some more forum posts I probably would have gone with the green one for better contrast.) Installed it with no issues. Polarization film had notches in the corner so it only fit one way. Screen was a little too washed out when I turned it on so I bought a bivert chip from the same website. Installed the chip with no issues. I followed instructions that said to turn the polarization film 90 degrees to correct the inversion from the chip. Screen seemed a "little" better contrast wise but I was still not pleased with the results. I double checked all my wiring to make sure everything was working correctly and it dawned on me how the polarization film affected the contrast dial. When I originally put in the polarization film with the backlight, it made it that when I scrolled the contrast wheel all the way up it inverted the screen and when I scrolled down it decreased the contrast so you could hardly see any pixels. Well, with the bivert chip installed I turned the polarization film BACK 90 degrees to how it was originally when I first installed the backlight. Now turning up on the contrast wheel made the pixels lighter and turning down would cause the screen to become inverted. But the surprising thing that happened is that contrast was dramatically boosted! I'm not really too sure how it all works, but it did.

TL;DR - If you have a backlight and bivert chip installed, try turning the polarization film 90 degrees and play around with the contrast, then turn it 90 degrees again and play around with the contrast. You may get surprising results!

switchie15 (author)enovah2015-02-22

Blue definitely has the trickiest contrast to adjust. You will have to play around with the orientation and dial to get it just right. The other colors are much easier to tune in.

enovah (author)switchie152015-02-23

Agreed! And I wanted to post all this just in case someone else ran into the same problems I had.

tvall made it! (author)2014-06-26

my first time doing any kind of soldering to surface mount components. took me forever to complete.

probably didn't help that i started working on it moments after getting out of bed. was too excited to wait.

Elementix (author)2014-06-18

I installed the bivert mod and the backlight and my screen is still inverted...what gives??

switchie15 (author)Elementix2014-06-18

The bivert mod inverts your screen to begin with. So you need to turn your film 90 degrees to make it normal again.

Elementix (author)2014-06-15

From what I read, the remaining pins should be tied to ground. Is this true, and just not shown??

switchie15 (author)Elementix2014-06-16

I would say yes, but iv'e never had a problem without grounding them.
