VVVVVV PC versions come with a folder called data, this folder should be copied to the appdata folder which should be something like /media/mysdcard/pandora/appdata/vvvvvv
Either create the folder or run the pnd once, then copy the data over.
Once the data is present you should just need to run the game.
Note: Previous users dont need to change anything, just get the pnd and play.
