 Some dumping tools, notably GodMode9 as of 2024-05-26, erroneously always write 0x00000000 into the position of the Cartridge ID2. This is presumably because the cartridge ID2 is always zero for retail carts.

 The CardDeviceReserved areas have random-looking data whose purpose is unknown, other than perhaps to hide the TitleKey.
-Note that a particular flashcard vendor puts what many refer to as "private headers" here in place of actual development card information. This header is constituted by a cartridge-unique ID obtained from [[Process_Services_PXI|pxi:ps9::GetRomId]] and the title-unique cart ID (identical for all carts of the same title; can be retrieved using the NTR gamecard protocol command 0x90 or through the CTR protocol commands 0x90 or 0xA2).
