microVU: 

- Implemented the tri-ace gamefix.

Note: I've only tested SO3 so-far and it has some ugly graphical problems with mVU. SO3 does some evil VU stuff that it shouldn't be doing, but it does them anyways xD
I know the cause of the problems, so I just have to code the solutions sometime in the future...

P.S. SO3 looks really funny with the FlagHack1 speedhack! The characters turn into floating heads effectively turning the game into PacMan xD
