this might sound stupid but honestly as far as i've seen no one has really named the homebrew except just homebrew why not name it homebrew 3d or 3d homebrew i dont know just something
@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
