Jpcsp SVN r2340 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:
r2335
Support several controllers having the same name (Issue 268).
r2336
Trying to avoid error "SceGeListEnqueue can't enqueue duplicate list address" in race condition when list is finishing.
r2337
Improvement in sceMpegRingbufferPut: do not put more packets than available in the MPEG stream.
r2338
Small improvement in sceKernelLockMutexXX: check for valid parameter and return correct error codes.
r2339
Ported sceGe_user module to new model.
Forgot Utilities file in r2336.
r2340
Improved the implementation of callbacks and interrupts:
- callbacks to be executed in a specific thread are only executed when this thread is scheduled according to its priority (previously, the thread was scheduled immediately)
- simpler implementation in the compiler Runtime.
This change improves the compatibility of callbacks, but might break existing games due to the new callback mechanism. Please report any change of behavior for playable games.
