Jpcsp is the advanced PlayStation Portable 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.
