[quote=95927]I’ve noticed that when using the recommended settings in the first post, Snes seems to fill the screen whereas master system, megadrive does not. Is there a reason for this?[/quote]
Sorry, I wasn’t able to replicate the problem on my system. Be sure to double check all settings. Hold “x” or “m” when launching a game to configure the video settings for that emulator – set video output to your monitor’s native resolution and set retroarch render res to 720. This has to be done for each emulator. Then enter the other settings via the retroarch GUI.
