Most SNES emulators currently have options to overclock the Super FX chip to 40MHz, 60MHz, 80MHz, and 100MHz. This makes many games (Star Fox is the common example) play much faster than intended.
I propose a 20MHz setting to allow games that use the original GSU-1 (or MARIO Chip) to receive a reasonable, playable speedup.
This video demonstrates the output of libretro-snes9x with snes9x_overclock set to "disabled, 20MHz (new), and 40MHz, respectively.
