PCSX2 SVN r4042 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:
r4041
Game Database Editor not needed yet.
r4042
New option to backup the old, existing savestate when creating a new one.
