I downloaded No$gba and Zoomer. When I try playing Yugioh 5ds 2011, it goes to a blank grey screen and stays there, so I tried playing two other games (Harvest Moon: Tale of Two Towns and Scribblenaughts), but they also get stuck at blank screens (not grey ones, though). I played all these games on Desmume, so they're not fake. I tried both No$gba and the Zoomer, but the same results. Any idea?
