JPCSP PSP emulator for Mac OS

JPCSP PSP emulator for Mac OS

Uploaded byRandAS


JPCSP is the most advanced Play Station Portable emulator, allowing you to play your PSP games on a Mac (see also Android and iOS version). 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.

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.

System requirements

System requirements may vary depending on your hardware configuration. For the best experience, users should be running within the recommended system requirements. We cannot guarantee the performance of system specifications below the minimum requirements, but you’re always welcome to experiment. Do not expect stable performance or consistent compatibility as changes are always being made to the codebase.

OS versionMac OS X – 10.14 or above

The table lists the minimum system requirements for running JPCSP emulator Mac OS


•Added support for an external software rendering engine

•Added a Java implementation for the audio decoding (Atrac3, Atrac3+, MP3 and AAC) which is improving the compatibility and makes the use of an external audio decoder obsolete

•Added network configuration settings

•A ProOnline server is now built-in within Jpcsp. It can be used to play in a local network

•Added support for the loading of demo games (large encrypted EBOOT.PBP)

•Several improvements in networking support: Compatibility of ProOnline network. Auto-detection of port shifting for running 2 Jpcsp on the same computer

•Added an experimental xBRZ plugin for improved 2D texture scaling

•Added support of kernel module so that many chinese patched game are worked

•Complete rewrite of the video modules (sceMpeg, scePsmfPlayer) for improved compatibility

•Added support to run the PSP original VSH interface

•Experimental support to run the original PSP complete boot process using Low Level Emulation (LLE). This method is able to run the official PSP 6.61 EBOOT.PBP and from there, the CFW PROC-C for 6.61
