Another step forward in the race to crack open the PSP: ps2nfo.com user Paradox worked out how to get a dump from a UMD disc, and has released the ISO files for several PSP games (Wipeout: Pure US, Ridge Racers Japanese, and Vampire Chronicles: The Chaos Tower Japanese). Also of note, UMD discs use the standard ISO9669 format, so the released ISOs can be burned to regular CDs or DVDs.
