PCSX2 SVN r4177 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:
r4175
Patch from avih, untested (but probably harmless) as I only have one monitor:

Make the GS window go full-screen on current monitor instead of always on primary monitor.
r4177
API change: Simplified handling of app/emu config defaults handling. Got rid of the mandatory "defaults" override -- LoadSave APIs for Pcsx2Config and EmuConfig now use the current settings of the class instead.
