Use GameCube cheats with NeoGamma

Hello, I just decided to make a guide today how to use GameCube cheats with NeoGamma. The advantage of NeoGamma is that you also can use them with backup discs.

Requirements:
-Latest NeoGamma version
-This package

Introduction:
Get the cheats you want to use, for example here, the cheats from this site are already in ocarina format and you can use them directly Just click on GCT, select the cheats you want and download the file, save it to "Neogamma/codes" or "codes". Then you can continue with Step 4. The problem is that they are not so many cheats on the site, most of them are in action replay format, for example from here or here. There are two formats of action replay codes, XXXXXXXX XXXXXXXX, that's already decrypted, then you can continue with step 2, the other format is XXXX-XXXX-XXXXX, that's encrypted, you need to follow step 1.

Step 1:
At first you need to start the "GCNcrypt.exe" to decrypt the code. Simply copy the code into the left box and click decrypt:


Step 2:
You now need to convert the decrypted action replay codes to ocarina. Start the "AR to WiiRD.jar", copy your code into the left box and click convert code types. If you decrypted the code with GCNcrypt you need to check the "Each code has a verifier line." checkbox, if the code already was decrypted leave it unchecked:


Step 3:
Now you got the ocarina code which we can use! Start the "codemanager.exe", click on "Add a code/comment/category", enter the code name, then add the code from step 2 into the code contents box, click store modifications and check the checkbox of the new code:


Now you need to get the game ID of the game. Just boot the game in neogamma, it will show you the game ID while booting:


Now click "Export to GCT" and enter the filename (in this case "GM4P01.gct"), save the file to "Neogamma/codes" or "codes".

Step 4:
This is the easiest step. Make sure you got the latest neogamma, go into the neogamma "Ocarina/Wiird" option, set "GC Hook Type" to "VI", "GC 2nd Hook" to "= 1st hook" and "GC Ocarina" to "Yes". After this you should be able to play the gamecube game with your codes you want to use! If they doesn't work try another hook type.

That's it! Bye, have fun using codes

this is nice. thanks for this.

This is just what I needed! Thanks so much!

Thanks. Very helpful.

Thanks I searched for this some years ago

Thanks for the positive feedback, great to hear it does the job fine
BTW I noticed that I can't use cheats from USB HDD for some reason, it just says no codes found.

can it work on retail discs too? or is it only on backup dvds? because ive added some codes and none of them will work, it saids the cheat codes found and appiled but they dont work... i tried all GC hooks too..

EDIT: NVM! i just had to install wiigator's CMIOS. it worked now, thanks for the help.

Thanks, works like a charm. I just used it to unlock the for the casual gamer nearly unobtainable AX Courses in F-Zero GX I also had to install the cMIOS (I didn't use  Neogamma before), maybe you can add that as a note in your guide.

I'm having major problems with Neogamma's cheat engine...Neither Gamecube mode or Wii mode seems to be working for me. I have the latest d2x CIOS with the recommended base, the latest cMIOS with MIOS-v10 as base, good ol' 3.2 System Menu.

I tried Super Smash Brothers Brawl off USB device with  Neogamma set to VBI Hook type and Ocarina on. Green Screen is what I got.

I tried Super Smash Brothers Melee off DVD-R with Neogamma set to VI Hook type and ocarina on. Green Screen again.

Other launchers worked great with cheats, but Neogamma is not. And if it weren't for the GC ocarina, I'd probably throw it away. Anything I could try?

You surely use the latest  neogamma r9 beta56?

Yeah I do. I even tried older versions but nothing seems to work...I'll try other games but I don't think they're going to work either: I saw  neogamma booting Brawl- mod before, so there is no reason it shouldn't work for me...

awesome, researched this years ago and couldn't find a simple way to do it, with this i can finally get those otherwise impossible to get NES games from animal crossing, worked great, thanks a lot!
