About:
bsnes is an emulator that began development on 10/14/2004. The purpose of the emulator is a bit different from other emulators: it focuses on accuracy, development (debugging tools), and clean code. Given this is a rather new project, it doesn't really achieve its goals very well yet.
The emulator does not focus on things that would hinder the accuracy area. This includes speed and compatibility. The minimum system requirements for bsnes are quite high, and the compatibility is roughly about 10-20% at present. Most of this is due to the missing spc700 apu, the rest are due to errors in the cpu emulation core.
To facilitate the clean code aspect, all development directly to the source code is done by me personally. Everyone has their own style of programming, and mixing these can quickly make code much harder to manage.
