Edit: I tried the game in an emulator and the boxes were rectangles there as well — I suppose they are meant to be rectangles, my bad. Still, does anyone know how to adjust the width of the image in the OSSC, similar to the zoom width option in the Framemeister? Is that possible with the OSSC?
When playing 4:3 games from my GameCube or N64 on the OSSC, I noticed that the image is being slightly stretched in the horizontal axis. Squares appears like rectangles and circles more like ovals because of this. Has anyone encountered this issue, and if so, do you know what causes it and how to fix it? I took this image to show the problem on my GameCube. I was using the 2x line multiplication mode.
