新版变动如下：
- Fixed bug in Z80 core, preventing some games from having sound (Wonderboy, etc.).
- Fixed bug in 68000 optimization, that could make some games hang (Bonanza Brothers, etc.).
- Changed sound handling and doubled sample rate for PCM sound, resulting in slightly better sound quality.
- HW renderer partially rewritten, many glitches should be gone, some are still there
- Sprite rendering completely rewritten in ASM. Should be faster and fix most of the sprite issues.
- Implemented mid frame palette updates (water effects in Sonic games, Castlevania, etc.).
- Many little optimizations in memory handling and the CPU cores.
- Added option for sprite masking (Landstalker etc.).
- Added option to change between 3- and 6-Button pad (just works, if the option is applied BEFORE loading a game).
- Added sound state to the savestates, so that the correct tracks should play now when a state is loaded.
