Free homebrew arcade games for the Nintendo DS platform. This is also where many ports, remakes and homages to classic games that are not FPS or platform titles will end up. Shmups will typically be found here too.
@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
