bsnes is a reliable Super Nintendo Entertainment System / Super Famicom emulator that focuses on accuracy and debugging functionality.
bsnes does not focus on things that would hinder accuracy. This includes speed and game-specific hacks for compatibility. As a result, the minimum system requirements for bsnes are quite high. Excluding unemulated special chips, the compatibility is now at around 99.25%.
bsnes itself was not derived from any existing emulator source code, such as SNES9x. It was written from scratch by myself. Any similarities to other emulators are merely coincidental.
