Jpcsp SVN r2377 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:

r2368 did broke the "-u" command line switch (reported by Hyakki): now fixed.

r2377
Ported a lot of syscalls to the new syscall model: EventFlag, LwMutex, Sema, SystemTime, CpuIntr.
Due to the recent native compiler support, this might improve the performance of some applications.
