Libretro is a simple but powerful development interface that allows for the easy creation of emulators, games and multimedia applications that can plug straight into any libretro-compatible frontend. This development interface is open to others so that they can run these pluggable emulator and game cores also in their own programs or devices.

bsnes/higan is a Super Nintendo Entertainment System / Super Famicom video game system emulator that aims to document SNES/SFC hardware with an extremely high degree of accuracy without compromise or optimisation.

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

As such, it has quite high system requirements. For a SNES/SFC libretro core that balances performance and accuracy to an acceptable level for 99% of games, consider using a snes9x core.

Three profiles are available: Performance, Balanced, and Accuracy. Balanced is recommended for modern PCs. Use Accuracy for extreme cases of hardware spec abuse (e.g. the game A.S.P. Air Strike Patrol).
