Introduction: How to Play Gamecube Backups on Your Wii Without a Modchip.

Picture of How to Play Gamecube Backups on Your Wii Without a Modchip.

Ever wish you could play those GameCube backups on your Wii? Well with my help you can.

How it works: The Wii has two modes; a wii mode that lets you play wii games and a GameCube mode that restricts the access of the wii to its wii systems and lets you play GameCube games. While in the Gamecube mode it is almost impossible to access most of the normal Wii functions, and most importantly, it is almost impossible to access any homebrew application. The rungcbackup.dol copies the gcbackup launcher to memory and changes to GameCube mode and also patches the DVD read functions in memory, to make reading DVR-r's in Gamecube mode possible. This is technically able to block your wii, but will most likely result in you not being able to play GameCube games, but this can be solved in the future when a GameCube Mios fixer/restorer is released.

Before you do this instructable you need to already have The Homebrew Channel, DVDx, Wii backup launcher 0.3 gamma with cIOS7 on your wii.
Since the process to do that is long and since someone else already posted an instructable how to do that, follow this instructable before you start to do this hack.
Note that the WII backup launcher is unable to play Gamecube backups, that's why you need Gamecube backup launcher to play Gamecube backups.


Wiigator (The actually author of Gamecube backup launcher 0.1 Theta/Xi and Wii backup launcher 0.3 gamma.) has a warning for all of us.
It is prohibited to use any of the software to illegally copy games, they are intended only to create and play legal backups of games that you own. In some countries or regions it is still illegal to make copies of games

that you own, check with your local authorities if you are unsure. I cannot be held responsible for any misuse of these programs. The use of any of the above software is done so at your own risk. If you mess

something up or anything undesirable (i.e.: loss of warranty, brick, lawsuits, jail time) happens because of any of these programs, it is your own fault. USE AT YOUR OWN RISK!!!!

If you have any questions at all it's better if you ask before you start messing with your Wii.

Step 1: Assemble Your Tools.

Picture of Assemble Your Tools.

You will need these items to successfully modify your wii to play Gamecube backups.

SD Card (Not SDHC)
Computer with SD card reader
Gamcube controller (to play the Gamecube games.)
DVD-r that can burned at 3x.
DVD-r burner. (imgburn)
RAR extractor (7zip )
Gamecube ISOs

Theta or Xi or .2
(All three versions work,with varying compatibility, some games work with Xi but not with .2,you'll just have to experiment.)

Step 2: Move to Files to an SD Card.

First, download the Gamecube backup launcher 0.2 RAR file to your desktop or a folder you can easily find. Then extract it with Winrar or 7-Zip.
Open the Gamecube backup launcher 0.2 Xi folder you got from extracting the RAR file, read the text file for some info, and open the "CONTENTS" folder.
Insert your wii SD card (with the Homebrew channel files and folders on it) into your computer.

Copy the "Apps" folder and the "RVL-mios-v8.wad" to the root of your SD card, if asked to merge folders, click yes.

Well you're done here! Just remove the SD card from your computer and insert it into the Wii.

Step 3: Installing It on Your Wii.

Picture of Installing It on Your Wii.

First turn on your wii. Select the homebrew channel from the Wii menu.
Then find the "cMIOS-res1-Installer" and click it. The screen will go black for a second and then some text will appear.

Press A on your wii remote to start the installation process.
Use the d-pad to select WAD installation mode.
Press A again.

Some text will appear, and wait until you see "Success". (This could take a minute).
Press any button to restart your Wii.
Insert your Gamecube backup DVD into your Wii.
Go to Homebrew channel again.
Click on GC Backup Launcher and then click load.

The screen will go green for a second while the Backup launcher loads.
Plug in your Gamecube controller and Gamecube memory card.
Press the A button on your Gamecube controller to auto-detect.
The screen will go green for a second and hopefully the backup will start.

Play your Gamecube Backup!

Step 4: Burning the Games.

Picture of Burning the Games.

Before you can play a Gamecube Backup you need to have a DVD-r and a Gamecube ISO. I can't tell you where to get the ISO but once you have it it's a simple matter to burn it to a DVD-r. You can use a regular 4.7gb DVD-r or use 1.37 gb mini disk (good luck finding any).

You can make a multi disk 4.7gb DVD-r to not use so many DVD's.
Why waste a 4.7 gb disk on a 1.36 gb game? You can easily shrink several games and place them on your 4.7gb dvd-r.

First download this.

Extract the files from the RAR.

Open the Gamecube multidisk ISO creator.

Use the ISO tab to add multiple games.

Check the shrink box if you want to fit extra games.

Select your Wii region (PAL,NTSC or JAPAN)

Click "Create Multiple Game ISO".

Name you file.

Select where you want to save.

Open imgburn.

Click on tools, then settings, a new window will pop up. Go to the write tab and uncheck the enable burn proof tab.

Close the settings window, click on write image file to desk, click on file and browse for source file, find the Gamecube ISO file, click on it once, then click open.

Change the write speed to 3x.

Insert your DVD and press the file to DVD button.

It will take about half and hour to burn a 4.7 gb size file.

Step 5: Troubleshooting.

Picture of Troubleshooting.

If any problems pop up I'll add them to this list.

Question: "Every time I start Gamecube backup launcher it gets a freaky green screen and reboots my wii."
Answer: " You either didn't install the miospatcher or forgot to put the Gamecube backup DVD in the wii before you started the Gamecube backup Homebrew app. "

Question: "Do DVD+R or DVD+RW DVDs work?"
Answer: "I had great success with both DVD+R and DVD-R, but I couldn't get my wii to read a DVD+RW DVD."

Question: "I play a game and it's black and white with flashing bars"
Answer: "You're playing a game that has a different region than your Wii, or a different region than your tv. "

Question: "My Gamecube files are GCMs not ISOs."
Answer: "You need to right click them, and rename the GCM part into ISO."

Question: "How do I switch games in a multidisk?"
Answer: "After you load Gamecube backup launcher use the D-pad on your Gamecube controller."

Question: "Can I play PAL or JAP games on my NTSC Wii or vise versa??"
Answer: "I didn't test that out , I'm pretty sure you can't yet but it won't hurt your Wii if you try.."

Question: "Which games are compatible?"
Answer: "Here is a list of most games that were tested. I personally can say that the NTSC versions of Pikmin, Pikmin 2 and Ty the Tasmanian tiger 3 work."

Question: "When I start GC backup launcher I get freaky lines and need to restart my Wii."
Answer: "This happens randomly, just restart the Wii and it should be fine."

Question: "MY SAVES DON'T WORK and/or ARE GONE!!!!"
Answer: "You probably downloaded Gamecube Backup launcher Theta and updated to Gamecube Backup launcher Xi. The save files created by Theta were named incorrectly and will not work in Xi. The problem has been fixed in Xi though, so it should work in future Gamecube backup launcher versions. "

Question: "There are people in your instructable that keeps commenting on your instructable with links to a site with something called 'HomebreWare' or 'Homebrew unlock hack', is it some sort of scam? "
Answer: "Yes, it most definitely is a scam. HomebreWare was started by some people that wanted to make money off the already free Homebrew Channel. They charge you a grotesque amount of money for a useless piece of software with claims and testimonials of how good it works only to disappoint you when it fails miserable on your updated wii firmware and bricks your Wii. Always remember, THE HOMEBREW CHANNEL IS FREE.

My Mario golf:Toadstool tour iso crashes after the intro.Is it a problem if i dont have a MEMORY CARD?

jaxxster1 (author)2011-11-25

will the wii still function normally? or will the regular gamecube setup be screwed?

bryden001 (author)2010-12-16

i downloaded the files, but what in the heck am i supposed to put on the sd card and how? Wii version: 4.2U, dont think that matters but jic.

choopengardner (author)bryden0012011-10-04

First off you need to home brew your Wii in order for this to work. To do that you need a SD card 2GB max. Then look up the rest on Google. After you have learned how to home brew your Wii and have done it. These steps should be entirely easy. I'm going to test this out in a few minutes, ill see if it works for myself.

abckookooman (author)2011-07-18

I'm not a pirate, and I'm doing this only to fit more games on 1 disc (I own he originals.)
what rate do I write data to the disc?

DVD+R can screw up the laser on the wii over a long period of time. (it still works though, but be careful)

dprobst1 (author)2011-06-02

I get an error when its reading my DVD. erre 0x3208 or something and it restarts my wii

matstermind (author)2011-05-18

for those who can't get this working, the newer wiis have a disk drive that CAN NOT PLAY BACKUPS OF ANY KIND FROM A SOFTMOD, in order to play gamecube or wii backups, you need a modchip

matstermind (author)matstermind2011-05-18

one thing you can do is use a usb loader, those work perfectly for wii games, but unfortunately don't work for gamecube games

alexthepwner (author)2011-03-11

PLEASE HELP when i put in any correctly burnt disk i think it says error 186 ir 187 and when i put in an actual gamecube disk it gives me the same error but loads after a few seconds

humongo_spork (author)2010-06-17

I have the same problem as Hillsidebro5. At first I thought it was a problem with the disc, but I burnt it again to a different disc and got the same result.

alexthepwner (author)2010-04-29

Zpeed (author)2010-04-26

I like Pikmins too, hope that they gona do Pikmin 3 :)

SharinganLust (author)2009-12-21

 Didn't work. xD; I'll explain some problems I noticed.

I tried installing the WAD installation, but one thing was wrong.

"Installing Custom MIOS, please wait...
        >> Installing ticket... ERROR! (ret = 2011)

[SUCCESS]: Custom MIOS installed successfully."

So I'm not sure if it's installed or not. All I can say it, I updated my Wii when I played New Super Mario Bros. Wii. So I'm not sure if that's why or not.

I'm positive I have an NTSC-U rom. Not sure if Paper Mario is compatible or not, seeing as the list was down. But anyway, I tried to run the game on the Backup runner and I got a giant green screen which restarted my Wii.

One of the three must have happened.

1. The Custom MIOS didn't install.
2. I burned the ISO wrong.
3. The game isn't compatable. 

Any help, pl0x?

Solderguy (author)SharinganLust2009-12-21

Well you must have firmware 4 or higher if you get an error 2011.
The error happens when you try to install an ios that relies on a trucha bug that was patched by Nintendo. You need to restore the trucha bug on your Wii console before you can install any CIOS or MIOS. Here is a good tutorial to restore the trucha bug on your Wii if you have firmware 4.0 or 4.1:
Follow this tutorial ONLY if you have FIRMWARE 4.2 ON YOUR WII:

After you're done restoring the trucha bug on your Wii, install the Mios again, and it should work.

SharinganLust (author)Solderguy2009-12-22

This guide seems very helpful, but there's one problem. It wants me to download V532, but only gives the option to download V523. Error on their part, or do I actually need v532? 

Solderguy (author)SharinganLust2009-12-22

The guide clearly says V523. I don't know where you got v532.

SharinganLust (author)Solderguy2009-12-22

I must have been hella messed up last night. xD;

But I do have another problem. This guide is confusing. I've downloaded all the WADS, the App, etc. I've gotten to the screen that says

Install an IOS that accepts fakesigning"

And I click the fakesigning option.

I've done everything up to "Load IOS from SD card." and it's saying after the first time "Getting IOS12 from 257." Okay, cool. Press it again and it tells me "IOS 15 Downgrade to revision: 257 complete! IOS 12 successfully downgraded! Continue to install your fakesign accepting ISO 36? Getting IOS36 revision 3351..."

So I press "Load ISO from sd Card" and I get something like this.

"Could not open (Suchandsuch WAD).wad
Could not open (Suchandsuch WAD.wad
error reading ISO into memory.
Failed. Restarting..." 

And takes me back to the homebrew channel.

I'm positive I've downloaded everything I needed from the guide. Any help again? And I'm so sorry I'm bugging you about this. -Sigh.- if you don't respond, I understand.

Solderguy (author)SharinganLust2009-12-22

Make sure you know what firmware version your Wii is. If it's firmware version 4.2 and you're doing the guide for 4.1 it won't work. Also make sure that the files are named correctly and in the right place on the SD card. If that doesn't work leave me another comment. I don't mind at all.  :D

SharinganLust (author)Solderguy2009-12-22

Just replaced and tried everything to no luck. xD; 

stomp_442 (author)SharinganLust2010-04-08

Just a heads up for everybody, never accept a disc update or an online update if you want to keep your softmods. Accepting an official Nintendo update will wipe out homebrew capabilities.

mastagkush (author)SharinganLust2010-01-22

You prob installed your ios wrong, instead of "wad installation" try "network installation"  if this is possible. i think thats the problem.. (just hit right to switch..)

SharinganLust (author)mastagkush2010-01-22

Why would I choose Network Installation instead of Wad Installation when it tells me to use Wad Installation? 

It may be that an updated version exists online that doesn't work on your wii. Downloading from online requires wifi, but gives you the latest wad available.

robot797 (author)2010-02-10

can somone tell me if this wil work with a hard disk or a memory stick

Solderguy (author)robot7972010-02-16

No,the Wii can only access the hardware needed to run gamecube games when it's in Gamecube mode. This is a hardware limitation.

robot797 (author)Solderguy2010-02-16


thank you...

emedd33 (author)2010-02-05

Is it posible with a Harddisc driver, while using USB loader, rather than a DVD?

Solderguy (author)emedd332010-02-16

No,the Wii can only access the hardware needed to run gamecube games when it's in Gamecube mode. This is a hardware limitation. (sorry it took so long to answer I was busy with school.)

r0ckf0x (author)2010-02-06

I have the same problem that bsltiger had but i dont  know how to fix it. help please!

Fran108 (author)2010-01-18

well i fixed all that but do you need the IOS thing? If so how can i install it via internet? I just really want to play some Paper Mario again.

Fran108 (author)2010-01-17

Ok i fixed it but now when i try to fid the iso i can't but it shows up when i open my downloads folder help again

Fran108 (author)2010-01-16

someting is wrong with my ISO creator it stops work in the middle of creating the ISO

SharinganLust (author)2009-12-25

Don't know if you got my comment or not, but it didn't work. xD: Any other suggestions, out of curiosity? 

Solderguy (author)SharinganLust2009-12-26

Sorry, I was busy with Christmas stuff. :P I'll be able to suggest what to do if you tell me what firmware is on your Wii. Until you do, I'm stumped. :O

SharinganLust (author)Solderguy2009-12-27

xD It's fine. My christmas was hectic, too. Especially the day after. -Sigh.-

But anyway. Ummm. My firmware is 4.1. 

... >>; Oyy? 

bsltiger (author)2009-12-23

when i start the cmios installer, my screen stays black. no words come up or anything. any idea on what i should do?

bsltiger (author)bsltiger2009-12-27

fixed. i uninstalled ios249 with anytitle deleter, then reinstalled with cios installer rev 14. started from step one again and now i can play wind waker!

splontot (author)2009-12-24

 Hey, I was wondering if this works with 4.0. I've gone through all of the steps and it doesn't work for me. I'm using DVD+R discs so I dunno if that may be the problem.

When I launch the GC backup app from homebrew it says it cant read the disc. 

If you have any info thanks in advance.

Solderguy (author)splontot2009-12-25

If it says that it can't read the disk then it's either the DVD is a cheap brand (Memorex) or you burned it incorrectly or at an incorrect speed. Try burning the DVD at a lower speed (2.4) and it might work.

splontot (author)Solderguy2009-12-25

 Okay thanks I'll try that, and if i were to use the normal backup launcher would that work? or does it have to be the gamecube one? if so do you have a link to it in a rar file? every one ive tried to download is in a file that my winrar cant open for some reason. 

VitaminB (author)2009-12-21

 Solderguy, you're my hero for keeping up with this and not letting it drop.  Haha But I have another question...  I installed everything, and it works fine.  I beat Metal Gear on it with no problems other than video and audio being unsynced at times during cut scenes.  That's okay with me, (if you have a way to fix it though, I'd be grateful) but now I'm trying to play Splinter Cell on it, and regardless of whether I choose Auto, or Specify NTSC, or press B to play with the patch, it won't work.  It gets through the menu, to the screen where you can choose to load a file, but when I try to start a mission, everything stops.  T.v. just goes black.  If I press "start" instead of A, Y, or B; then it works okay. Ish.  It's really dark compared to how it should be, and I have no ability to change the brightness.  Also, after every mission the game will save, after I save and it's about to load the next mission, the wii stops just like normal.  Then I have to go back, reload everything, press start, and continue the game.  After every mission.  What'd I do wrong? D:

(Also, I don't know if it makes a difference, but the file was originally a .gcm file, and I changed it to .iso by renaming it.)

SharinganLust (author)2009-12-17

Just two more quick questions again and I'm done. xD;

Out of the three progs (Theta, Xi, and Xi v2), which one do you really recommend? I noticed you were using Xi v2 when explaining the installation process and whatnot.

Also, this one might be a stupid question. Does it matter what type of DVDs? I can only burn +R,s unfortunately. 

Solderguy (author)SharinganLust2009-12-17

I would recommend Xi V2, because it's the newest and has the best compatibility
The Wii can play both DVD-r and DVD+r, but it prefers DVD+r.

SharinganLust (author)Solderguy2009-12-17

Then it works out to my advantage. =D Thank you so much. Very appreciated.
