An experimental open source HLE PSP Emulator released.

Quote:
Features: (end-user point of view Smile
- Plays Puzzle Bobble Pocket JAP
- Starts AI Go
- Runs numerous demos from the PSP SDK

Technical Features:
- Badly simulated PSP kernel
- Mounts ISOs and CSOs (no DAX!)
- Mounts Windows directories (no good UI yet for this)
I haven't test it with my psp isos but how ? I will read the readme soon when I have time. I am very busy right now.
