News: Downloadable PSP games in the works?

It looks like (legally) downloadable PSP games could maybe, possibly be getting ever so slightly closer to reality, as a Sony-made ISO loader has reportedly been discovered in the latest firmware update for the handheld. The current speculation is that the loader, discovered by the prolific Dark_Alex, gives the handheld the ability to load encrypted ISO images off a memory stick, not just the demos and PS1 games the handheld's currently capable of playing.
