higan

higan is an emulator for multiple video game consoles, including the Super Nintendo Entertainment System.
Themaister came out of retirement to collaborate with byuu on an upstream-friendly libretro-ization of higan. Currently, only the SNES emulator is available, but we hope to extend this to include all of his suite of emulators. Only the mainline ‘accuracy’ profile is available from the Online Updater currently, but we hope to add hex_usr’s ‘balanced’ profile soon. In the meantime, you can get it pre-compiled for Windows from his nSide github repo.
Notably, the higan core includes Super Game Boy support, including all special features, such as borders and music.
