− | + | ===Main CPU=== | |
− | + | The main SNES CPU ran at 3.58 MHz and 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."<ref name="SNES overclock">http://web.archive.org/web/20070629163744/http://www.undergroundcm.com/index.php?option=com_content&task=view&id=15&Itemid=38</ref> | |

− | + | There are no SNES emulators that allow for an overclocking option, likely because of those issues. | |
− | + | ===SFX chip=== | |
− | |||
The first version of the chip, commonly referred to as simply "Super FX", is clocked with a 21 MHz signal, but an internal clock speed divider halves it to 10.5 MHz. Later on, the design was revised to become the Super FX GSU-2; this, unlike the first Super FX chip revision, is able to reach 21 MHz. | The first version of the chip, commonly referred to as simply "Super FX", is clocked with a 21 MHz signal, but an internal clock speed divider halves it to 10.5 MHz.
