Description

On NES and SNES emulation, enable Maintain aspect ratio follows 8:7 PAR, that would stretch horizontal pixel to perfect 2048 (256x8), but current BizHawk stretched it to 2051 instead, a little longer than 8:7 PAR expected size.

Research direction

Reproduce the NES and SNES display with Maintain aspect ratio enabled and compare the current width with the expected 8:7 PAR result. Trace the aspect-ratio calculation from the emulator display path; done when the horizontal width is 2048 rather than 2051 for the stated 256x8 case.
