Reply To: SNES correct aspect ratio in Generic 4:3 mode Line4x

[marqs]

What do you mean by ‘correct’ aspect ratio? Equivalent on how it’d look on a CRT or something closer to 8:7?

If you want to fit SNES image horizontally, then your sampling rate needs to be h.active/0.75. To fit vertically, v.active needs to be 224 (a few games would need 240, though). Then your display would need to be able to scale resulting 1280×896 resolution into whichever aspect you consider correct (4:3 or 8:7). For compatibility reasons default parameters have been selected so that resulting resolution is 1280×960 with small borders on each side but with aspect that should be close to CRT when PAR is preserved by the display.
