BSNES has a somewhat different purpose to most emulators; it focuses on accuracy over performance. To that end, it does not include any game specific hacks, or idle-loop skipping optimizations commonly found in other emulators. To add to the fun, it uses a cycle accurate hardware emulation. The net result of all this is the highest system requirements of any software I've released to date; those without an Intel-based Mac need not apply. If you meet the requirements, however, this is the most accurate SNES emulation available on the Macintosh platform.
