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

~~@Neimod, then what exists between 0x1000 and 0x4000 and what would you call it?--[[User:3dsguy|3dsguy]] 17:09, 28 July 2012 (CEST)~~

: It's called the card info header, returned by gamecards when reading the header. I'm also finding your updates not always accurate because you are working only with development files, which differ sometimes greatly with retail files. If you look closely, you'll see that retail card info header is 0x200 bytes, while the development card info header is much much bigger. --[[User:Neimod|Neimod]] 20:46, 28 July 2012 (CEST)

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.
