Bsnes displaying darker colors than other cores?

In order, Snes9x, Bsnes, Beettle and Mesen-S.

Anyone know why Bsnes is the odd one out here? I’ve been told Bsnes is supposed to be the most accurate of the snes emulators.

If I remember correctly, bsnes does gamma correction by default, which is indeed accurate behavior compared to an SNES connected to a CRT. It can probably be disabled inside the core options, just look for any entry labelled with “gamma”.

It’s not accurate to anything, it’s just a pleasing effect that Near really liked and borrowed from an ooooold SNES emu called “Super Sleuth”.

There’s a direct port of the code in shader form here:

libretro/slang-shaders/blob/master/misc/shaders/ss-gamma-ramp.slang

I didn’t know the backstory. Thought byuu just strived for the average CRT gamma correction. Thanks for sharing!
