JPCSP: Java PSP Emulator

About:

JPCSP is the most advanced PlayStation Portable emulator, allowing you to play your PSP games on a PC. JPCSP has been started in July 2008 and is developed by a small but active team.

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.

NVIDIA graphic cards are fully supported and Jpcsp can take advantage of powerful GPUs. Problems have been reported with ATI/AMD graphic cards: keep you Catalyst driver up-to-date as new releases might fix issues.

The project is still a beta release, but currently more than 600 games are already playable. See the list on the official Forum.

Video and Atrac3 sound are supported. Atrac3+ sound is not directly supported as there is currently no free codec available for this format. However, Atrac3+ can be decoded automatically on Windows when installing SonicStage.

Requeriments:

Be sure to have JRE (Java Runtime Environment) installed in your computer before attempting to run JPCSP.

It is strongly advised that even on a 64-bit OS, you should install the 32-bit JRE release and use JPCSP’s 32-bit version, for compatiblity reasons.

If after installing the JRE you get the following message:

• “If you already installed the JRE then you need to set up the JAVA_HOME variable and add to the PATH with \bin like this: %JAVA_HOME%\bin”

You need to add JAVA_HOME variable manually in Windows 10/11: HERE IS THE TUTORIAL.

IMPORTANT: Make sure to check the README file inside the emulator folder. It has all the necessary information about configuration, issues, etc.

The x86/32bits version of the Java 8 and JPCSP has better compatibility with Win 10/11.
