PCSX2 SVN r4765 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.

PCSX2 SVN Changelog:
r4762
SPU2-X: Reverted back to the last version of the reverb engine before the rewrite plus some backwards lerp fixes (accident in optimisation in r2089). Thanks to gigaherz (I guess? This is mostly your fault.)
r4763
SPU2-X: Oops, I'm the one who spotted this when we were discussing it too.
r4764
SPU2-X: Tried to fix the incorrect bitshifts back from when Neill's code was optimised while the registers were broken so it wasn't testable. My maths is probably off, the code needs reviewing. The "- 1"s are so that -1 * -1 = just short of 1 instead of -1 (overflow).

With this, reverb maybe sounds somewhat like the PS2 for the first time ever!?
r4765
SPU2-X: I was being silly, those -1s are unnecessary (I was thinking we were downcasting for some reason).
