Hey, Rayder, is it still possible to obtain your cheat database? All the links on your post are dead. I know that you haven't done this in 9 years, but we'd still like the actual files.
@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
