This is a list of important system files or other data.
| Filename | Name in essential.exefs | Path in GodMode9 | Purpose | Importance |
|---|---|---|---|---|
LocalFriendCodeSeed_B
|
frndseed
|
1:/rw/sys/LocalFriendCodeSeed_B
|
Used to identify the console for online play. | Bans from online play are effectively bans on the LFCS. (Don't ask here or NH for help on how to get unbanned.) |
HWCAL0.dat and HWCAL1.dat
|
hwcal0 and hwcal1
|
S:/ro/sys/HWCAL0.dat and S:/ro/sys/HWCAL1.dat
|
Contains hardware calibration data. Parts of this are put into the Config savegame during first-time setup. | If this file is lost or taken from a different console, then when the console is formatted, the calibration data will be inaccurate and can result in problems such as flickering screens. |
movable.sed
|
movable
|
1:/private/movable.sed
|
Contains data that is used to encrypt digital games and saves on the SD card. Also used for CMACs on various NAND files. | Keeping a backup of this is important if you want to ensure you can still recover your old saves if your console is lost or broken! |
| NAND CID | nand_cid
|
M:/nand_cid.mem
|
Used as part of the NAND encryption. | This can be used to decrypt a NAND backup on a PC, however it's not strictly required for 99.9% of cases. |
| NAND header | nand_hdr
|
S:/nand_hdr.bin
|
Contains information on the NAND partitions. The console-unique part here include the TWL MBR, which is encrypted per-console. | Corrupting this will prevent the console from starting. However GodMode9 can generate a new one in its place if you can use it through something like ntrboot. |
| OTP | otp
|
M:/otp.mem and M:/otp_dec.mem
|
Contains various kinds of console-unique data. Used to generate encryption keys and identifies a console in some cases like the eShop. See also: 3dbrew:OTP Registers | This is required to decrypt a NAND backup on a PC. Sharing this means someone could impersonate your console to Nintendo, so don't post it in a public space! |
SecureInfo_A or SecureInfo_B
|
secinfo
|
S:/rw/sys/SecureInfo_A or S:/rw/sys/SecureInfo_B
|
Used to identify the console in some cases like the eShop. | Sharing this means someone could impersonate your console to Nintendo, so don't post it in a public space! |
