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 FIRM_SYSCOREVER, and these two values don't match, [[AM:InstallNATIVEFIRM]] will return an error.

−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 field are clear. [[ErrDisp]] will display development error info when bit0 is clear.

−When this field is zero, bit0 for UNITINFO is set for retail. When this field is non-zero, bit0 for UNITINFO is clear for dev/debug units, and an ARM11 kernel state flag which enables debugging is set. JTAG is only enabled for debugger and "firm" modes (bit1).
