has released a custom firmware plug-in for the PSP that allows users to easily save and load decrypted savedata from UMD titles. Once decrypted, savedata can then be modified directly in any standard hex editor.
In addition to the usual bug fixes, version 1.10 includes vastly improved compatibility, along with a new feature that allows users to patch and overwrite the SFO params/info on save.

UPDATE 19.02.2008: v1.10
* Did some mayor internal changes due to huge compatibility issues when actually running/using the plugin.
Should be way more stable now, hopefully running on 100% (or at least 99.9% ) of the games.
Also it's only one .PRX now, not splitted in two anymore, since the main .PRX is now a native kernel mode one.
* The usual minor bug fixes
* Added a new feature to patch/overwrite the SFO params/info on save (see readme)
