Wood R4 works with the patches as long as you disable cheats and resets on the settings menu.
Although, it does freeze if you catch a Pokemon, view your Pokemon Roster or any Summaries, so it's pretty useless...
@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
