These are the same as the application's main [[NCCH#CXI|CXI]], except the ExeFS/RomFS only contains files which were updated. When loading NCCH data the system will load from the update-data title by default, and if the data doesn't exist in the update-data title the system will fall-back to using the data stored in the original application CXI. The programID stored in the NCCH header matches the NCCH titleID, however the programID stored in the exheader is set to the original application programID instead.
