Jpcsp SVN r2448 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:

Small fix in software renderer
r2448
Found 2 small errors in the vertex shader while reviewing it to implement the software renderer.
This might have a slight impact on the lighting effects generated by the shader.
