Here's the latest update of PCSP, the PSP emulator for Windows, written in C++. Though its not a pretty siginicant upgrade as the team explains below, its good to know that they are still trying to improve this PSP emulator.

Developer's note:

Althought we have already announced the total rewrite of pcsp from scratch to provide better support (some parts was really bad in pcsp) , this is the last release of pcsp based on old source.
Be warned this version isn't supported from pcsp team since we have moved our effords to the new pcsp rewrite. It is also quite possible to see a preview of the new pcsp in a few days , but also be warned that new pcsp doesn't run commercial games yet.
