okay I was wrong.
Now, My stuff already came weeks ago and it works fantastically on gba rom support. And now my superkey will come in tomorrow. Do I need to know anything about nds roms when I test out this baby? Like, do I have to convert it like I did the gba roms?
Yes, the NDS roms will need to be patched.
Patching doesn't always work for some DS games though. That is where slot-1 flash cards come into play.
Okay, I'm all set. Thank you guys.
