PCSX2 SVN r3423 is released. PCSX2 is an open source PlayStation 2 (PS2) emulator for the Microsoft Windows and Linux operating systems. With the most recent versions, many PS2 games are playable (although speed limitations have made play-to-completion tests for many games impractical), and several games are claimed to have full functionality.

We overshot the final pre-clamp shift by one bit. Should be final now ;)

Now Area 51 works :P Ok this probably fixes Tekken 4 properly, id missed some bits when moving some of the code over, which would have caused it not to work right, plus my favourite = instead of == slipped in..
