For those that still have crashes, try to not use "Alt+Tab" combinations... I noticed that always i did that, my emulator crashes with the next dialogue...
Sorry my bad english
@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
