If you’re in the PSP homebrew community and have an unlocke PSP, a new version of the KVM J2ME virtual machine has been released.
This little software allows you to play J2ME games on the PSP, extending the core MIDP 2.0 API of J2ME with some vendor-specific libraries, like the Nokia API.
The mobile games scenario has its moments, so this little software will probably find a permanent place in my own PSP.
