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 a G5 class machine need not apply. If you meet the requirements, however, this is the most accurate SNES emulation available on the Macintosh platform.
- This release officially introduces the accuracy and performance cores, alongside the previously-existing compatibility core. The accuracy core allows the most accurate SNES emulation ever seen, with every last processor running at the lowest possible clock synchronization level. The performance core allows slower computers the chance to finally use BSNES. It is capable of attaining full frame rate on all official Intel Macs.
- The accuracy core is absolutely not meant for casual gaming at all. It is meant solely for getting as close to 100% perfection as possible, no matter the cost to speed. It should only be used for testing, development or debugging.
- The compatibility core is identical to previous releases of BSNES, but is now roughly 10% faster. This is the default and recommended core for casual gaming.
- The performance core contains an entirely new S-CPU core, with range-tested IRQs; and uses blargg's heavily-optimized S-DSP core directly. Although there are very minor accuracy tradeoffs to increase speed, I am confident that the performance core is still more accurate and compatible than any other SNES emulator. The S-CPU, S-SMP, S-DSP, SuperFX and SA-1 processors are all clock-based, just as in the accuracy and compatibility cores; and as always, there are zero game-specific hacks. Its compatibility is still well above 99%, running even the most challenging games flawlessly.
- A future release will embed all three emulation cores into one binary, but that will involve some code refactoring that would have delayed this update for several weeks. Please note that saved states are not transportable between emulation cores, and in the current release attempting to load a state in the wrong core will give a generic error message.
