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.
Hidden bootrom off-switch
ARM9 bootrom 0xFFFF8000+ is disabled by writing 1 to (u8*)0x10000000 and 1 to (u8*)0x10000001?
0x10010000
NATIVE_FIRM writes value 1 here when a FIRM launch begins.
REG_UNITINFO
This 8-bit register is value zero for retail, non-zero for dev/debug units.
