While I think PCSX2 could stand some improvement (its Linux port is well behind the Windows one, and even getting it to build is a huge pain due to lack of 64 bit support) I don't think this project is going to be it. I'm pretty dubious on the choice of Java as well; PCSX2 needs a pretty quick CPU as it is, and if it ran at even half the speed that could be the difference between playable FPS and not.
