Sleepper has released PSPKVM v0.1.0 — a JavaME VM capable of running mobile j2me apps/games on the PSP. Once you get the hang of PSPKVM’s control scheme, you’ll no doubt find games much more enjoyable than using your phone’s keypad — especially those still sportin’ the Nokia 3650.

To use: start PSPKVM and select a “.jar” file. The default device is the SE K800i; press Triangle to cycle through available devices. The last selected device will be loaded on the next boot.

Stay tuned for improved versions of PSPKVM; it’s said the author of pspME, M@x, will be merging his project with Sleepper’s in effort to provide a better Java Micro Edition Virtual Machine for the PSP.
