With the Servers for the game now defunct, there is no way to get community created content. This file contains 58 levels which I still had downloaded in my save game so I figured I'd upload them so others can enjoy them, too.
This has been tested on Title PCSF00076, I don't know if it will work on other versions of the game.
Just open your save game decrypted using vita shell and copy the "offline" folder and patchfile.json into your decrypted PCSF00076 savegame folder.
Obviously overwriting existing files in your savegame will remove any existing community levels. So back them up before replacing them with these.
