I have this r4 www.r4ultra.com
I tried using ttds and ysmenu. The game booted on one of those dont remember. but after character it went black screen.
Now they just released a kernel. How do I play on this r4!!
@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
