I tried GbaEmu4DS (Whatever it's called, I think this site features it) and I boot up Pokemon Fire Red, Just Putting Certain Options... BAM! Red Screen. Also I've noticed on the R4 Pokemon Black 2/White 2 Freezing/Crashing (Usually When I Move The DS) and also Certain Homebrew Games Not Working... Such as: Any DS Game Maker Game. (The Screen Flickers White For 1/4 A Second Then Black Screens & Stays Like That) Oh... A Typo...
