same thing happened to me:
52 with 222-mload and Hermes 222 v5 was stable
updated to 53a and got the crash right after cfg-loader bootscreen
reverting to 52
and - i love the loader
@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
