All of these fields are initialized by the ARM11 kernel, except for MENUTID and ACTIVEMENUTID which are set by NS.

=== KERNELVERSIONMINOR ===
=== KERNEL_VERSIONMINOR / FIRM_VERSIONMINOR ===
This is the kernel version-minor, this likely isn't obtained from the [[FIRM]] title-version.
This is the [[FIRM]] version-minor, this likely isn't obtained from the [[FIRM]] title-version.
=== FIRMVERSIONMINOR ===
=== KERNEL_VERSIONMAJOR ===
This is the ((title-version & 0x3FF) >> 4), for the currently running [[FIRM]].
This is the ((title-version & 0x3FF) >> 4), for the currently running [[FIRM]].
=== FIRMVERSIONMAJOR ===
=== FIRM_VERSIONMAJOR ===
This is the same as KERNELVERSIONMAJOR. After [[AM:InstallNATIVEFIRM]] checks FIRMSYSCOREVER, [[AM:InstallNATIVEFIRM]] then compares FIRMVERSIONMAJOR with the NATIVE_FIRM ((title-version & 0x3FF) >> 4), when the latter is larger than FIRMVERSIONMAJOR [[AM:InstallNATIVEFIRM]] will trigger a FIRM install.

=== UPDATEFLAG ===
=== UPDATEFLAG ===
When launching [[NCCH#CXI|CXIs]], the value stored here must match the core version field stored in the CXI exheader. If they do not match, the [[Process Manager Ports|PM]] module will refuse to launch the ARM11 process. The regular ARM11 kernel sets this to 0x2, while the SAFE_MODE ARM11 kernel sets this to 0x3.

=== FIRMSYSCOREVER ===
=== FIRM_SYSCOREVER ===
Normally this is the same as SYSCOREVER. This used by [[AM:InstallNATIVEFIRM]] for comparing with the NATIVE_FIRM titleID-low. When the low u8 from the NATIVE_FIRM titleID-low is larger than FIRMSYSCOREVER, [[AM:InstallNATIVEFIRM]] will trigger FIRM installing. When that u8 is not larger than FIRMSYSCOREVER, and these two values don't match, [[AM:InstallNATIVEFIRM]] will return an error.

=== UNITINFO ===
=== UNITINFO ===
Normally this register is all-zero, however bit1 in this field is set by the ARM11 kernel when ARM debug CP14 DSCR bit14 is set. [[NS]] loads the menu TID from MENUTID when bits 1-7 of this register are clear. [[ErrDisp]] will display development error info when bit0 is clear.

=== KERNEL_CTRSDKVERSION / FIRM_CTRSDKVERSION ===
This is the CTR-SDK version which was used to build the currently running [[FIRM]].
