This CVer titleID/title-version is from the CVer [[CIA]] stored in the [[System Update CFA]]. With newer NATIVE_FIRM versions the system reads this 0x200-byte block from offset 0x200 in the NCSD image, however the CVer fields are not used.

The ExHeader Sha-256 hash and ExHeader Size for the NCSD header is always zero, why?--3dsguy 07:33, 28 July 2012 (CEST)

Old version:

Offset Size Description
0x200 4 Always 0xFFFFFFFF
0x204 252 Padding?
0x300 4 Used ROM size in bytes
0x304 28 Padding
0x320 8 CVer Title ID (Only Present in retail .CCI)
0x328 8 CVer Title Version (Only Present in retail .CCI)

This CVer titleID/title-version is from the CVer CIA stored in the System Update CFA. With newer NATIVE_FIRM versions the system reads this 0x200-byte block from offset 0x200 in the NCSD image, however the CVer fields are not used.

Old Version? Is this not present in new retail game dumps?--3dsguy 03:48, 29 July 2012 (CEST)
