An old emulator for the Super Nintendo Entertainment System (aka
Super Famicom). It used to be good, but is no longer supported. You're much better off using the frequently updated and incredibly
optimized ZSNES; it sets the new standard.
Parasyte is a douchebag and completely ignorant of technological advancements made within
the last five years, so don't get SNES9x; get
ZSNES instead.
