Inaccurate 1:1 PAR scaling

[TheFilthySilver]

It appears that the Beetle Saturn core for RetroArch incorrectly scales up to the wrong aspect ratio. The core incorrectly assumes that every games are displayed in 352x240. When running Saturn Bomberman, the 1:1 PAR on RetroArch results in the game appearing in the wrong aspect ratio. When running the same game on Mednafen on "aspect_int" setting, the game appears in the correct aspect ratio.

RetroArch 1:1 PAR

Mednafen aspect_int

Unless the issue is to do with RetroArch itself, can you fix the 1:1 PAR setting for the core please?

Looks like the horizontal res and aspect ratio are both assuming 352 width all the time: https://github.com/libretro/beetle-saturn-libretro/blob/master/libretro.cpp#L984
