JPCSP
What it is
JPCSP is a free PlayStation Portable emulator written in Java, with project work dating to 2008. The listed platforms are Windows, Linux, and macOS; the download page specifically lists Windows and Linux builds in 32-bit and 64-bit versions. Its v0.7 changelog records software rendering, graphics performance improvements, frame skipping, texture modding, and game pad support. It also lists automatic decoding of stereo ATRAC3+ audio using SonicStage and improvements to the integrated debugger. For networking, the changelog says ad hoc play works between two JPCSP instances, but not with a real PSP; PlayStation Network sign-in is unsupported. The maker provides a compatibility page with game listings. The site links to a forum and the project’s GitHub repository. JPCSP is listed as free, with no paid plans listed. The site maintainer says downloads are imported automatically from JPCSP GitHub Actions and that HTTPS was enabled and forced during the website’s restoration.
