It isn’t the ROMs though. I tried the same ROMs (Super Metroid, Super Mario World, Mario Kart, Chrono Trigger, Sonic & Mario 64) in the snes9x, nemu64 & Gens32 emulators (respectively) on my laptop, they play fine with no discolouration. That is part of why I am at a loss. I thought it was the ROMs…. but it isn’t.
