Over at French speaking site PSPGen, one of their users has made a release today that is sure to rock the PSP world. Homebrew devs CipherUpdate and Kono have released NP Decryptor, a program capable of breaking the PSN store's DRM on PSP titles such as fl0w and Beats. The authors tell us a little about the app in the readme.

Quote:

This is a psp homebrew to decrypt psp games bought from the Playstation Nework Store.
Only those that are real psp games, not psone, can be decrypted with this tool.
Only psp that can play the game can decrypt it. After decryption it can be played on whatever psp running a CFW.
This homebrew has only been tested in 3.90, we don't know if can works on other CFW.

Basically the only person that can break the DRM is someone who has the license stored in the flash3 partition of their PSP. The authors go on to tell us the exact use of this app.

Quote:

Locate EBOOT.PBP of the game to decrypt and change its name to NP.PBP
Copy EBOOT.PBP and npeg.prx from this release in that folder.
Run NpegDecryptor. The game will be decrypted to the ISO folder with some name as "NPEG-XXXXX.iso" "NPUG-XXXXXX.iso"...
After decryption, you can play the iso game normally as you would do with other iso, try various umd modes if one don't work.

This certainly a big release and it will be interesting to see how Sony attempts to counter.
