marshallh from the benheck.com forums has managed to overclock a Super FX chip. The Super FX was an extra graphics processor included in some Super Nintendo games. Using this chip, games like Star Fox were able to handle polygons and intensive sprite scaling. marshallh removed the 21.4Mhz ceramic resonator from a Vortex cartridge and replaced it with a 24Mhz oscillator and a couple caps. The result is a smoother frame rate and minimal slow down with multiple enemies.
