I have both a DS and DSLite and I want to start putting ROMs on it as opposed to carrying my entire game library with me everywhere. I know that you need a flash cart (I think I will get an Acekard2i) and an sd card, but is there anything else that you need? I just want to play DS games and maybe put a GBA or SNES emulator on there. Do I need a passcard? Thanks for clearing it up.
