PSPKVM is a free Java 2 Micro Edition emulator for PlayStation Portable.

Overview[edit]

PSPKVM is in a project to enable MIDP/JavaME applications such as mobile games, to run on PSP. Originally developed by sleeper, the project was merged with pspMe on February 12 2008.The two developers decided to continue by keeping the better advantage from both projects. On March 31, before April Fools, they updated the KVM to version 0.3.0 slightly increasing the interface and playable applications. PSPKVM is a PSP port of Sun's open-source JavaME implementation phoneMEFeature. The objective of the phoneME project is to further expand the usage of Java Platform, Micro Edition (Java ME platform) technology in the mobile handset market. The project scope includes a focus on the mainstream feature phone segment with phoneME Feature software, and the emerging advanced phone segment with phoneME Advanced software. Our goal in making these technologies available to the Mobile & Embedded Community is to reduce implementation variation, increase the rate of innovation and enable new devices to leverage the power of the Java ME platform.

Known issues[edit]

  • Not running on 5.02 Gen-A firmware
  • javacall_file_truncate isn't ported, so some file truncating operations, including some RMS operations, may not work as expected
  • Multimedia temporary files may be left on your memory stick occasionally, especially after a VM crash. They're usually not big, but if you want to delete them manually, go to your PSP's /PSP/GAME/pspkvm/ directory, find the files whose names look like xxxxxxxx_tmp_mus.mid, and delete them.
  • Fileconnection rmdir operation may fail for unknown reasons.
  • LocationProvider.getState() will always return AVAILABLE once the GPS is initialized, so LocationListener.providerStateChanged() doesn't work as expected.
