Okay so had a quick poke around and found this (please be aware I'm not at home and therefore have NOT tested this is any way):
It includes rev-emu 9.76RC1
All the present files are exactly whats needed to play after apply the update. Only some issues with emulator make this a pre-release.
At this time the know Issues are related to
an error popup window while loading the game to main menu, just alt-tab to desktop click ok and go back to game. it should load normally then.
Next known issue is when loading a map. It will show again the error pop ups.so accept them again and keep back to game and play.
