PCSX2 SVN r3746 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:
r3745
Fix for some major slowdowns present in dev/debug modes when using trace logging features.
r3746
* Simplified VIFunpack's C-based interpreters (removed ODD size handlers and unused data)
* Fixed V2/V3 unpacks to behave same as the SSE unpacks (matches undefined PS2 behaviors)
* Removed legacy vifUnpacker (haven't needed it for any regression testing in forever).
* Move some VIF MARK console spam to DevCon (Ape Escape 3)
