NCSD images start with a NCSD header, followed by up to a maximum of 8 [[NCCH]] partitions. The first partition([[NCCH]] 0) usually starts at 0x4000, this is generally the main [[NCCH#CXI|NCCH]] (Executable). The following info on partitions 1, 2, and 7 are only valid for .CCI. The second partition([[NCCH]] 1) contains the game "Manual"(title ID for the .[[NCCH#CFA|CFA]] containing the Manual always starts with '0005'). The third partition([[NCCH]] 2) contains the download play "Child"(The title ID for the .[[NCCH#CFA|CFA]] containing the DLP Child always starts with '0006'). The eighth block([[NCCH]] 7) contains "Update Data"(The title ID for the .[[NCCH#CFA|CFA]] containing the Update Data always starts with '8000') The format of partitions can be determined from the partition FS flags, while the contents can be determined from the partitions flags.
