V4.9 : 17-Feb-2025 by wavemotion-dave
- High Score (HSC) auto-save improvements - no longer write the backing .hsc file if the write didn't actually change HSC data.
- Improved Sally emulation accuracy and optimization pass to render the games 3-4% faster.
- Improved Pokey emulation - missing sounds on games like Ballblazer are now much better.
- Improved memory emulation for more accurate mirror handling - 7800 Utility cart now shows this as a PASS.
- Improved memory caching to help with the really big games (those 512K or larger).
- All but two games on the DSi are now rendered without any form of frameskip. Older DS-Lite/Phat reduces frameskip due to new optimizations.
