Higan is a series of Nintendo emulators that takes the term ‘emulator‘ really, really seriously. It attempts to maximize fidelity to the original machines as much as humanly possible. On the one hand, this makes for better emulation performance. On the other hand, it makes the program a bit more finicky to set up and is a more intense resource draw. Higan supports NES, SNES, all flavors of Gameboy, as well as the DS emulation.
Verdict: While not necessarily the best as a primary choice of emulator, higan makes for an excellent backup emulator if you’ve got something your normal emulator won’t run.
