ISO loader found in PSP update

The latest firmware update for the PlayStation Portable has been found to include an ISO loader which would allow users to play games stored on Memory Stick.

The np9660.prx file was discovered by coders in the v3.50 and v3.51 updates released last month, which also unlock the PSP's full 333 MHz processing power.

With an ISO loader, PSP owners would be able to play games without the need for a UMD. However, Sony has yet to confirm whether the new update is part of plans to make games available for download via the PSP Store.
