Jpcsp SVN r2349 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:
r2348
Possible problem due to the new callback mechanism fixed: execute correctly the callback, even in the context of an idle thread.
r2349
Migrated the compiler options to the new settings model. They can be changed "on the fly" (e.g. Max method size).
