Jpcsp SVN r2347 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:
r2345
Completely reworked the option settings and patches handling. Now every Jpcsp option (from Settings.properties) can be set in a game specific patch file (patches/.properties).

Some options can already be changed "on the fly", i.e. while a game is running. But this is not yet complete. Also an "Apply" button is still missing in the options GUI (to apply changes "on the fly" without closing the options dialog).
r2346
Implemented the new HLE module interface (reflection) into the compiler: syscall methods are now directly called by the compiler without going through the SyscallHandler.
This brings back the performance lost by the introduction of the new HLE interface. This is however almost not noticeable in commercial applications. Showing a 50% improvement on syscall using compilerPerf.
r2347
Avoid error "BBOX Invalid vertex address 0x00000000". This is valid at GE initialization.
