Jpcsp is the most advanced PlayStation Portable emulator, allowing you to play your PSP games on a PC. Even though Jpcsp is written in Java, it can already reach 100% PSP speed on a lot of commercial games... and the emulator performance is constantly increasing.
Here's the changelog from 3 latest SVN builds:
+More progress on adhoc networking: implemented sceNetAdhocMatchingSendData, sceNetAdhocMatchingGetHelloOpt, sceNetAdhocMatchingSetHelloOpt, sceNetAdhocctlConnect, sceNetAdhocctlGetPeerList.
+ Still only communicating between two Jpcsp, not a real PSP.
+Implemented a lot of missing CW cheat codes.
+ Fixed NullPointerException raised in ClassSpecializer when enabling the software rendering.
+ The java compiler used by ant for the build distribution is not producing the same code as the java compiler started from my eclipse workbench: eclipse was generating only TABLESWITCH instructions whereas ant is generating LOOKUPSWITCH instructions!
