Ok. I know this question is asked alot so I apologize to those will yell at me, but I'm looking to see what people would advise as the best NDS flashcart for me. I'd like one that can use at least an 8gig sd card, play NDS and GBA games, work as an MP3 player, play homebrew, etc all from slot 1? does this exist? Is it better to have another cart in slot 2 for GBA?
