When I try to record SNES games through my Raspberry pi 3 the output video is changed to a multiple screen grid system showing 18 screens all displaying my SNES game. If I hit record it records all 18 screens. How do I make the output video only one screen? What displays on my Tv is one screen but through OBS the Screen Splits into 18 different screens. This screen split only happens with with SNES games. It stays one screen with NES, PSX, and Sega Megadrive games.
