Dai-2-Ji Super Robot Taisen OG (BLJS10133)

There are several encrypted .sdat files inside /PS3_GAME/USRDIR/PSARC/ (and maybe also other places in the game folder). Each and everyone of them will have to be decrypted manually, see for instance general instructions here: http://www.emunewz.net/forum/showthread....#pid239972

So I am suppose to manually decrypte each file ? Or I can do it with all of them at the same time ?
