It may seem useless to inject .gba roms into any other console because people would say that it's useless because emulators exist for both. This is my thought though... If there exists a way to do this it would be possible to make custom Wii Channel WADs to play Gameboy Advance games on. Any...
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
