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

A disc game is a game that comes on a disc, that is not downloaded from PSN. This is a disc game so it shouldn't be on the internal PS3 HDD (which is what the folder dev_hdd0 represents). Make a folder called PS3_GAME and put the file PS3_DISC.SFB next to that folder, and put USRDIR and the rest inside it.
