I'm hoping it may be possible to use the IR port for a universal remote control.
it'd be awesome to be able to turn off a TV/radio/whatever that's playing something annoying wherever i go=p
@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
