PCSX2 SVN r4967 (http://www.emucr.com/) is released. PCSX2 (http://www.emucr.com/) is an open source PlayStation 2 (PS2) emulator (http://www.emucr.com/) 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.

GSdx: Added a simple workaround for the 32-bit z problem talked about in the
comments of r4956. Since sprites are flat and there was an unused vertex member
(t.w), I just decided to pass the raw uint32 value in that to the scanline
drawing function. It does not fix triangles and other primitive types, of
course. The ideal solution would be to break z into two parts (like 8:24 bits,
and only care about the upper part when not zero), interpolate separately and
rejoin when needed, it is just too hard to add another variable when the
assembly code is already so tightly optimized to use every register.

(HW mode z-test expects a float input, so this trick cannot be done there.)
GSdx: Just remembered triangles were occasionally converted to sprites, need to
set t.w there as well.
