PCSX2 Rev.822 is released.PCSX2 is a 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 Rev.822 Changelog：
- r822 Nneeve worked a bit on our lovely floating point cpu's (mis)ability to do rsqrt the way the ps2 does. Should be better now ;) Today (88 minutes ago) ramapcsx2
- r821 wxgui branch: Full merge of trunk into the new wxgui, including a revision from way long ago that somehow got missed (when I renamed Windows folders in some plugin dirs) Today (9 hours ago) Jake.Stine
- r820 Linux: Make some of the assembly look a bit better. Change the PCSX2_ALIGNED_EXTERN defs a bit. Today (10 hours ago) arcum42
- r819 Fix for some random slowdown introduced in 815 (bad cacheline coloring caused a random 30% speed drop when not using speedhacks) >_< Today (10 hours ago) Jake.Stine
- r818 Linux: Fix a minor breakage in the gui code I just noticed... Today (11 hours ago) arcum42
- r817 A few very minor comment cleanups; getting all my code branches in sync for when I hit the road today. Today (12 hours ago) Jake.Stine
- r816 LilyPad: Svn release builds now have svn numbers, some configuration load/save/populate code cleanup. Two additional checkboxes that at the moment do absolutely nothing useful, so don't get too excited, probably be quite a while before I get around to hooking everything up... Today (14 hours ago) mattmenke
- r815 Major overhaul of the savestate system! Since backwards compat of savestates got totally broken a few revisions ago anyway, I decided to take this opportunity to revamp the savestate system with some significant cleanups (yes it loses all backward compat once again). Improvements include: * Reduced state size by removing some unneeded data (faster saves now too!) * Added string tags to varios "sections" of the states to assist in troubleshooting and retaining savestate compat in future vers Today (16 hours ago) Jake.Stine
- r814 More changes to the IOP's memory model. Some of these are experimental and might cause problems (needs testing). Quick rundown: * The R3000 does not have a TLB, and has no valid addresses mapped above page 0x2000 in physical memory [lower 512M]. Thus all addresses can have the top 6 bits masked off and still retain full validity. For example, address 0xbfc0 is simply a mirror of physical address 0x1fc0. Technically speaking, a full emulation of the IOP memory model would raise bus error ex Yesterday (17 hours ago) Jake.Stine
- r813 Implemented more correct support for the IOP's "isc bit" (bit 16 on the COP0 status register), which in turn allowed me to simpify some of the IOP's memory access and paging logic. Yesterday (22 hours ago) Jake.Stine "
