* Has a fork of bsnes known as bsnes-mercury, which aims to restore functionality like HLE DSP chip emulation and SGB emulation using Gambatte that was removed in later versions of bsnes, as well as have some optimizations that don't affect emulation accuracy. It also has an option to overclock SuperFX. Default options make it exactly the same as regular bsnes, with LLE DSP chip emulation enabled.
