PCSX2 SVN r4843 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:
r4841
SPU2-X: Clean up some logging code.
r4842
SPU2X: Better control of debug messages. (Now they actually print when enable at the SPU2X debug GUI).
r4843
SPUX: New stretcher: Should be slightly more stable now, compared to r4840.

On 4840 I added dynamic tuning (which may have slight negative effect on stability) to adapt to different iterations/sec of different systems, but I didn't like this system too much. On 4840 I also made a small change which, I now understand, factors out the differences between systems in this regard, essentially making dynamic tuning not required anymore. So now dynamic tuning is disabled.

If you enable the SPU2X messages (and the overrun messages), you would see log messages similar to this:

buffers: 44 ms ( 89%), tempo: 1.000000, comp: 1.000, iters: 764, (N-IPS:750 -> avg:50, minokc:50, div:100)

If the iters value (764 at this example) on your system when running at 100% speed (50/60fps) is higher than 1000 or lower than 500, then please comment here and post few of the log lines.
