Depending on the gamecard controller that has been selected, one of the following gamecard registers will become active:
- Selecting NTRCARD will activate the register space at 0x10164000.
- Selecting CTRCARD1 will activate the register space at 0x10004000.
- Selecting CTRCARD2 will activate the register space at 0x10005000.
REG_SYSPROT9
Writing values to SYSPROT sets the specified bitmask. The ARM9 bootrom(+0x8000) is disabled by writing bit0. bit1 is used by NATIVE_FIRM to make sure console-unique TWL AES-keys are only set at hard-boot. It is not possible to set any other bits.
REG_SYSPROT11
ARM11 bootrom (+0x8000) is disabled by writing bit0. It is not possible to set any other bits.
0x10010000
Initially this is value zero. NATIVE_FIRM writes value 1 here when a FIRM launch begins. The LGY FIRM writes value 3 here when handling PXI command 0x00020080(first TWL PXI command), it also writes value 7 here when handling PXI command 0x00030080(first AGB PXI command). This register can be read to determine what "mode" the system is running under: hard-boot, FIRM launch, or TWL/AGB FIRM.
REG_UNITINFO
This 8-bit register is value zero for retail, non-zero for dev/debug units.
