How to play:
1. Transfer to an external FAT32 media (pendrive/USB HDD) or over FTP
2. Use MultiMan's File Manager to copy the contents of FIX folder to /dev_hdd0/home/00000001/exdata/
The folder '00000001' is your user profile id. If you have only one profile -- that is the only folder you'll see under /home/ catalog.
In case you have multiple profiles, copy the *.edat file to the one that you will be playing the game from.
If the folder 'exdata' is not present that means you've never been logged to PSN -- create it manually and put fixed file in it.
3. Install pkg through Install Package Files
4. Play full version of Shank through XMB!
Deathspank TOV works the same way, with the fix being an .edat file. Don't know how many other games use this curious method.
The first I saw of this .edat file installation was with Shank, and it worked fine...
