Couple months ago, Sony mentioned that a PlayStation Network-like service was coming to the PSP. No details on what exactly would be available on this download service were given, only that it was coming soon.

Now, Mathieulh has uncovered a tiny module named np9660.prx in both Firmware 3.50 and 3.51. This module is none other than an official ISO loader by Sony, used to load encrypted ISO files off the memory stick.

If this discovery is any indication, one can assume Sony will begin to offer purchasable downloads of PSP games on the new download service scheduled to hit later this year.

Next OE to feature full NO-UMD emulation thanks to… Sony! [Devsgen]
