@ -19,6 +19,7 @@
- Remove 16MB of WRAM at 0x01****** from arm9. Maped to unusued instead. What was this? [zeromus]
- Change SPU to run two spus in parallel. SPU_core is the official one. SPU_user produces output.
This lets us do inaccurate things with SPU_user which might sound better while being more accurate with SPU_core. [zeromus]
- Add RTC implementations (not fully) [CrazyMax]
Mac OS X port:
- Fixed: Filenames and paths with unicode characters now work. [Jeff]
- Fixed: Load state from file button works again. [Jeff]
