My DS is a little wonky. The down on the D-Pad isn't very quick to respond, and my CycloEvo and/or EZflash 3n1 are buggin, not always booting correctly. If I got a DSi, what are the compatible flashcarts, and what method is there for playing GBA games? Is the built-in DSi music player decent, or any way to get it to play real music like .mp3s? Or should I stick with lmp-ng 2 alpha?
