Oh, it's pricy? How much is it usually? I got my Acecard 2 years ago for under $20 online.
If it costs more than $40-$50, I might be better off just buying some old used DS.
By this point I already bought most of the games for the 3DS games I'm interested in so the primary interest in a flashcard would be for games not localized.
However I recently just found my Acecard 2 filled with DS games. Does it not work since my 3DS is currently updated to the latest...
@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
