These commands are an interface for Process_Services_PXI.
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.
PS module does not use any CheckNew3DS commands: commands 0x000E0082..0x00110042 are handled by PS module regardless of whether this is running on Old3DS/New3DS. Using these commands on Old3DS will result in Process9 returning an invalid command header error. NFC module uses all of these new commands for New3DS.
