I'm getting a DS very shortly, and I'm delighted to see that (with the right equipment) I can play all my old GBA roms on it. How does button configeration work for GBA games played on a DS. I only ask because I've got my fingers crossed that I'll be able to play StreetFighter Alpha 3 with all 6 buttons on the DS. I suspect that I'm not going to get the answer that I would like, so let me down gently. Take it easy folks.
