Hellcat released this CFW plugin to save and load unencrypted savedata from any game.

Changes:

Did some major 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)
