I updated the SS Mednafen core today and the screen is somewhat messed up. There is a big border in the left side of the screen and the right side is covered. You can sort of fix the left side but the right side will always cover part of the graphics.
Looks like it was shifted to the right and is stretched horizontally more in certain games like Asuka and Leynos 2.
0.9.39.2:
0.9.43:
There were some overscan and aspect ratio options added to stand alone after 0.9.39.2 that should let you change this. They would just have to be exposed as core options. From stand alone’s changelog:
December 10, 2016: SS: Added setting “ss.h_overscan”, default value of “1”, to allow the user to show less of the screen on the left and right sides by setting it to “0”.
December 9, 2016: SS: Added setting “ss.correct_aspect”, default value of “1”, to allow the user to disable aspect ratio correction(not recommended, but whatever~).
Probably something starting here.
libretro.cpp perhaps needs some modifications.
edit: It should be back to how it was now. Cropping was ON and it’s not working in libretro atm.
