Nintendo (NES)

???

SNES

Main CPU

The main SNES CPU can be overclocked. However it causes issues. With those who have tested it, the following issues occur:

• 4.1 MHz: Small amounts of sprite breakup occasionally; very little slowdown.

• 5.1 MHz: Sprite breakup; no slowdown

• 6.6 MHz: Color palette errors; sprites fail to render

• 7.6 MHz: Color palette errors; sprites fail to render. Freezes after a few minutes.

There are no SNES emulators that allow for an overclocking option, likely because of those issues.

SFX chip

The SFX chip however can be overclocked with fewer issues on real hardware or emulation.

Snes9x-Next allows for SFX overclocking.

N64

Mupen64Plus - VI Refresh

GameCube/Wii

Dolphin - VBeam Speed Hack doubles GPU clock rate.

PS2

PCSX2 - VU Cycle Stealing allows for increased GPU performance at the cost of CPU cycles.

Neo Geo

Final burn alpha. Issues???

Mega Drive

Can be overclocked leading to faster/smoother gameplay. http://www.youtube.com/watch?v=SVrElANZg2M

No MegaDrive emulator currently supports overclocking.

The GenPlusGX dev says that implementing overclocking is "not easy to add without potentially break other things. "
