You know, how when you play a GBC game on GBA, you can hit L or R to Stretch it across the screen, so you don't just have black screen around it? Can you do the same for the DS? Might make some games look funny, but I think it works better most of the time .. I played GBC Zelda games on GBA and it looked good.
Also what screen will the game play on, top or bottom, and whats on the other screen while you play?
