Recent builds of [[Dolphin]] support supports overclocking and underclocking the CPU. Overclocking can remove slowdown from games that have them, pushing them closer to their actual locked frameratetarget frame rate. It causes several issues with many games, so don't expect it to be a perfect solution.
The [http://aamirm.hacking-cult.org/www/regen.html Regen emulator ] allows overclocking in the dev build version.<ref>http://segaretro.org/Regen</ref> Games with sprite flicker, like Altered Beast, and games with slowdown, like Rambo III or Mega Man: The Wily Wars, play perfectly with Regen's "Overclock M68000" setting at 732 (1.5x original speed). The game speed and audio are unaffected by overclocking.

==Famicom (NES)==Overclocking is possible on real hardware, but no doing so also speeds up the audio. No NES emulator allows for itoverclocking.

Dolphin used to have a VBeam Speed Hack that doubled GPU clock rate. This has since been removed, as the developers found that it didn't really help in any cases.
==PS2==
On fat older PS2's original model PS2s you can overclock by a small amount without too much problem, the biggest issue will be sped up audio. Slim model PS2's PS2s use the GPU's clockrate as a base for the CPU (multiplying the GPU's clock by 2), so overclocking the CPU will also overclock the GPU resulting in many visual problems.<ref name="PS2OC">http://nfggames.com/forum2/index.php?topic=2220.0</ref>
PCSX2 uses the CPU clock as a base, and divides for GPU clockrate, so overclocking will result in visual problems too, as well as sped up audio. [http://www.mediafire.com/download/u204iktybl9z2t4/Pcsx2_OC.rar PCSX2 OC Builds] [[PCSX2]] Also . The emulator also has a speed hack called VU Cycle Stealing, which allows for increased GPU performance at the cost of CPU cycles. It does give gives an incorrect FPS readout, though.
==PSP==
Final burn alpha allows for overclocking of Neo Geo games. MAMEUIFX (aka MAME32FX) also allows for overclocking.<ref>http://mame32fx.altervista.org/home.htm</ref> All Neo Geo should run at full speed when overclocked.
==Mega DriveSega Genesis==
The original hardware can be overclocked leading to faster/smoother gameplay. <ref>http://www.youtube.com/watch?v=SVrElANZg2M</ref>
Most Genesis emulators don't allow overclocking. The [[Genesis Plus GX]] dev , for instance, says that implementing overclocking is "not easy to add without potentially break other things. "<ref>https://code.google.com/p/genplus-gx/issues/detail?id=223</ref>
