Jpcsp SVN r2360 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:
r2358
Avoid "ConcurrentModificationException" while accessing VideoEngine.videoTextures from parallel threads.
r2359
Added an "Apply" button to the configuration settings. It saves and applies the settings without closing the dialog. Currently, only a few settings can be changed "on the fly" (i.e. without having to restart Jpcsp), but their number will soon increase...
r2360
Region settings can be modified "on the fly" if this is supported by the game (most probably only read the settings only at the startup).
