+== REG_EXTMEMCNT9 ==
+This register is presumably New3DS-only. Only bit0 is writable: 0 = disable New3DS ARM9 memory at 0x08100000 size 0x80000, 1 = enable.
+
+This bit is set by New3DS ARM9-kernel crt0.
+
+The data in this extended memory doesn't change when disabling the memory, then re-enabling the memory.
