So I set up retropie mostly so I could play my old gameboy games (who doeesn’t love super mario land 2) and I have ried everything to make the games full screen but nothing works. the image is always right in the center on my 48 inch TV.
I downloaded a prebuilt retropie image from this site. I used V2.3 . Do i need to update somehow? or should i try installing it from a normal raspbian linux?
