I couldn't find any real NDS light flashcarts on Amazon.com or other quick shipping online retailers. Any chance a Best Buy or other local store will have something like an R4? Or do I have to order from R4 or DStwo directly?
@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
