Thanks for the info, this is really helpful. I will try to remove the video choice when I get home. I don't fully understand how video resolutions work in RetroPie / FPZ. The panel itself is limited to 320 x 240 right? But you are reading the data off HDMI and telling it to output to 1024x768? When it hits the FPZ screen, it downgrades to 320 x 240? Does this mean the system is "overworking" itself to output a higher resolution only to be downgraded when it hits the LCD? Or does it work differently?
Update: So I think your trick to remove/reset the resolution settings worked. I can play the SNES games again!
