PCSX2 SVN r2055 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 SVN Changelog:
r2045
aligned_stack: Finished conversion of all CALLFunc and _callFunctionArg1 functions to aligned-stack safe __fastcall invocations; only IOP's psxExecute and dispatchers remain to be done. (rev is fully functional in this state tho, on win32 at least)
r2046
aligned_stack: synced with trunk, to bring in the new console code for additional testing under a (properly working!) linux.
r2047
aligned_stack: Linux has never worked so well!
* made a workaround for some obscure GCC templating bug
* Fixes the assert from PersistentThread when starting the emu
r2048
aligned_stack: Implement full compliment of stack alignment options for the IOP (untested in gcc/linux yet); and fix a compiler error in MSVC.
r2049
aligned_stack:
* Added -fno-strict-aliasing to the ever growing list of gcc optimizations that can potentially cause perfectly good C code to generate entirely broken results.
* Removed the preferred-stack=2, since this branch *should* run fine without it now.
* Have Release builds in Linux SIGKILL when encountering an unexpected SIGSEGV.
* Fixed some deadlock issues with the new console logger (it introduced cancel points, which is a good thing! unless you're the EE recompiler and you swallow up any attempt by GCC to cancel a thread)
* Compilation error fixes.
r2050
GSdx:
Fix Xenosaga 2 and 3 fog effect, not sure it's handled correctly but at least it's handled.
r2051
GSdx: Fixed a memory leak in m_weavebob when changing interlacing modes (same thing that caused the m_merge leak -- I chose to delete instead of recycle since I doubt the texture would be useful for anything besides the 1-time interlacing setup, so no point cluttering the pool with it).
r2052
Why didn't I think of this sooner? Added a pre-alpha announce when starting PCSX2 0.9.7 for the first time.
Also: Minor fixes to the console logger (Win7 report of corrupted cursor)
r2053
aligned_stack: sync with trunk, preping for merge.
r2054
Reintegrated 'aligned_stack' branch. General summary [interesting to Devs only,really]:
* EEcore recompiler aligns the stack on entry for all platforms.
* IOP recompiler aligns stack for GCC/Mac by default (can be force-enabled for all platforms via compiler define)
* Added setjmp/longjmp to the EEcore recompiler, used by GCC to exit the recompiler in efficient form (Win32 platforms use SEH).
* aR3000a.S and aR5900.S removed and replaced with x86Emitter generated dispatchers.
* All C functions called from recompiled code use __fastcall (simple, fast, retains stack alignment in neat fashion)
r2055
GSdx:
Added a somewhat more accurate upscale option via GSdx.ini. Not tested much! :p
