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.[1]
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.

No MegaDrive emulator currently supports overclocking.
The GenPlusGX dev says that implementing overclocking is "not easy to add without potentially break other things. "[2]
