Hello. Just out of curiosity, have you ever put up your 3DNES emulator project for github? I understand that it's most likely dead but it'd be neat to put the source out for those willing to tinker and expand upon it.
@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
