bsnes-mercury is a Super Nintendo video game system emulator that can be used as a libretro core.

Background

bsnes-mercury is a fork of bsnes aiming to restore some useful features that have been removed, as well as improving performance a bit. Maximum accuracy is still uncompromisable; anything that affects accuracy is optional and off by default.

These are libretro features, not frontend or standalone emulator features.
