PCSX2 SVN r4878 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:
r4876
MFIFO Changes:
* Vif: Altered how resumed transfers are handled slightly on VIF side (for
MFIFO).
* SPR: Now transfers data to the MFIFO even if not in MFIFO mode if it meets the conditions of the ring buffer location (SOCOM 2) SOCOM 2 is now playable, sort of, the HUD is a mess (unless a tip shows up), looks like Path3 masking but isn't.

Better alter this actually, there will always be one picky game which buggers this up ;p
r4878
Gamefix: Added gamefix for SOCOM 2 HUD corruption.
The game attempts to loads all data in to the VIF FIFO then stall it. Something goes very wrong. Maybe one day ill replace this and the transformers gamefix with a FIFO we can turn on, but for now, this'll do.
