→Extra Scanlines, SuperFX and SA-1
Existing SNES emulators sometimes allowed overclocking the SNES CPU by a fixed amount, but it was done in a way that would either increase the video and audio rate, or break games.
bsnes and Mesen-S now feature a new way of overclocking that comes from the NES emulation scene: inserting additional scanlines into the CPU thread, without running the video and audio during this time. The result is a method of removing slowdown in just about any SNES game, without any framerate or pitch distortion, and without harming compatibility in 99% of games (even streaming audio games such as Tales of Phantasia work as expected.)
The [[Wikipedia:List_of_Super_NES_enhancement_chips#SA1|SA-1 ]] and SuperFX can also be overclocked in this way. The other coprocessors ([[Wikipedia:List_of_Super_NES_enhancement_chips#DSP-1|DSP-1]], [[Wikipedia:List_of_Super_NES_enhancement_chips#Cx4|Cx4]], etc) support HLE which results in all of their operations occurring.<ref>[https://gbatemp.net/threads/bsnes-and-mesen-s-add-newly-developed-snes-overclocking-method.545475/ bsnes and Mesen-S add newly developed SNES overclocking method]</ref>
