I have the above mentioned emulator for gba on my psp but I can't for the life of me after lots of research, figure out how to get cheats to work. Specifically unlimited rare candies for Pokémon FireRed. Help!
@Xdqwerty, Osu! Tatakae! Ouendan! is the Japanese version of the game, different settings/characters/songs but otherwise identical mechanics. I played that before I knew about Elite Beat Agents lol. Both fantastic games https://en.wikipedia.org/wiki/Osu!_Tatakae!_Ouendan
