Jpcsp SVN r2313 is released. JPCSP is the most advanced PlayStation Portable(PSP) emulator, allowing you to play your PSP games on a PC. Even though Jpcsp is written in Java, it can already reach 100% PSP speed on a lot of commercial games... and the emulator performance is constantly increasing. Jpcsp takes full advantage of dual-core processors, matching the PSP dual-core architecture. Even a quad-core can give a small performance improvement by leaving free CPU cores for the Java JIT Compiler and the graphics cache.

Jpcsp SVN changelog:
r2311
Fixed sceUmdActivate: the UMD callback is not executed immediately, but at the next sceXXXXCB syscall. Tested on a PSP using "umdcallback" demo.
Fixed sceGeListSync/sceGeDrawSync: callbacks are not executed while the thread is blocked.
r2312
HLEFunction: added "checkDispathThreadEnabled" parameter checking if the dispatch thread is enabled.
sceKernelLockMutex: return error if dispatch thread is disabled.
r2313
VPL handling: moved some messages from WARN to DEBUG. Some applications try to free invalid addresses on purpose (e.g. trying to free an address from all available VPL's until one succeeds).
