From what I know, you can put both GBA roms and NDS roms on there. My question is, are you able trade with other games with these roms? For instance, if I got the Acekard 2i, slipped it into my ds, and attempted to trade with another ds that had Pokemon Soul Silver in it, would I successfully be able to do it? And, the same type of question goes for GBA/GBC games.
