For GetRomId, GetRomId2, and GetRomMakerCode, PS-module uses [[FS:GetProgramLaunchInfo]] with the processID which was sent to PS-module via the command input. If GetProgramLaunchInfo fails, PS-module returns error 0xC90107FA. When the mediatype is value2 for gamecard, the PSPXI command is used, otherwise PS-module just clears the output data for the command response.
