Since no one posted about this game yet:
40gb Fat PS3 (CECHG I believe)
Kmeaw 3.55 (Went from 3.41 OFW to 3.55 OFW to Kmeaw)
Two Worlds II (EUR)
Works from internal/external with latest Multiman/Gaia with disc (never tried discless).
One caveat: you must install the game data from internal, after that it will work from external just fine. For some reason it is unable to install game data from external. If you tried this be sure to delete the game data then run from internal. After that there should be no problems.
