+This could be referring to the ROM on the AR6K wireless chip:
+- Some 2DS units have the WiFi chip soldered directly to the board (such as the 2DS in this FCC filing: https://fccid.link/BKE/FTR001N), and some do not.
+- The AR6K ROM only acts as an initial loader.
+- Maybe some AR6K-family devices allow signature checks on the firmware? Or maybe some registers weren't write-once but should have been?
