With goomba I turned Zelda: Link's Awakening DX into a GBA rom which I then injected with your guide. Although -z isn't used any longer as it seems it worked like a charm and I'm happy to focus on that great game once I finished A Link to the Past.As long as your game compresses down to 8 megabytes or less (you can test by zipping your ROM to get a general idea, but obviously, don't feed this script the zip file, give it the raw gba file), here's how I did it:
- Open command prompt/terminal window
Code:python inject_gba.py -z alldata.bin your-rom-file.gba
If you've used Python, before it's no different than running any other scripts, really. Just use -z if you have The Minish Cap as your base game, or -m if you have Mario.
- Put your-rom-file.adb that you get from the Python script onto your SD card where appropriate (/wiiu/games/your-gba-game/content) and rename it to alldata.bin
- Run game through Loadiine
Edit: As a side-note, FireRed works great, but you can't save. C'mon Nintendo, support more save formats!
Just to let you guys know that this thread is a great solution to even play all Gameboy (Color) games on your Wii U.
