PCSX2 SVN r4083 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:
r4083
microVU: Implemented indirect jump address caching (speedup)

Indirect jumps (JR/JALR) get a table which stores the previously jumped-to x86 code entry points, and this table is indexed by the jump-to PC address.
If current jump is jumping to a previously jumped-to address, the table will have an entry-point, but before it is returned, the microProgram for which the entry point belongs to must be validated to see if it matches the current contents of VU memory.
The program validation check is remembered and doesn't need to be performed again until after a micro memory clear (which happens when vif writes to vu micro memory).
