JPCSP : Java PSP Emulator is the first PSP emulator that is written in JAVA. Most people think java is too slow. But Shadow and his team has proven us wrong. The newest Java versions are almost as fast as C which makes it very interesting for emu dev's. Shadow and his team are working day and night with pleasure on the emu, many coders have dedicated to the project. Because it's written in java many young devs find it interesting to learn how the emulator works.

Jpcsp is a PlayStation Portable emulator for PC, started by shadow (the same outstanding person that made PCSX & PCSX2) and joined by a outstanding team. Jpcsp is the first psp emulator written in java, allowing to play your psp games on a PC.

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.

Loading/Running applications:
To load an ISO/CSO image, you need to place it under the "umdimages" folder (this folder can be changed under Options > Configuration > General). For homebrew, place the application's main folder (which should contain the EBOOT file) under ms0 > PSP > GAME.

To know which games are currently compatible with the emulator, you can check JPCSP's forum for the latest news and an updated compatibility list post. The games tagged as "Encrypted" cannot be loaded by regular means. The only legal option is to own a PSP and use it to decrypt your own games' boot file.
