Post 3.x

Command Header, starting with 3.0.0-5 Available since system version Description
0x003B00C2 1.0.0-0 GetLegacyRomHeader
0x003C0102 1.0.0-0 GetLegacyBannerData
0x00440002 2.0.0-2 ExportIntegrityVerificationSeed
0x00450002 2.0.0-2 ImportIntegrityVerificationSeed
0x00490102 2.0.0-2 ReadSpecialFile
0x004B0000 3.0.0-5 GetMovableSedHashedKeyYRandomData
0x004A0040 2.0.0-2 GetSpecialFileSize. cmd[1] = must be value 0x0. Writes the u64 size to cmdreply[2-3].
0x004D01C4 3.0.0-5 ReadFileWrapper. If the first ReadFile call fails, this calls ReadFile again then executes hash-related code.
0x004E0204 3.0.0-5 This is a wrapper for WriteFile, this is similar to command 0x004D01C4.
0x004F.... 3.0.0-5 (unknown_u64)
0x00500000 3.0.0-5 Stubbed, this only returns value 0.
0x0051.... 3.0.0-5 (unknown_u8)
0x00520042 3.0.0-5 EnumerateSystemSaveData
0x00530000 3.0.0-5 Unknown, stubbed with 4.0.0-7.
0x0054.... 4.0.0-7 Stubbed with 4.0.0-7.
0x00550082 4.0.0-7 ReadNandReport (outbuffersize, u8 mediatype, outbufferptr)
0x00560102 9.6.0-X This calls some archive-class vtable funcptr, for the specified archive-handle. It's unknown what this is for.

Errors

Error-code Description
0xC82044BE Object does already exist/failed to create object.
0xC86044D2 Failed to write file. Partition is full.
0xC8804478 Object doesn't exist / failed to open object(file). Or: The specified title does not exist in the database.
0xC880448D FSPXI: Gamecard not inserted when attempting to use the gamecard.
0xC88044AB SDMC/NAND bus error, REG_SDSTATUS: TMIO_STAT_CMD_BUSY or TMIO_STAT_TXUNDERRUN
0xC88044AC SDMC/NAND bus error, REG_SDSTATUS: TMIO_STAT_ILL_FUNC
0xC92044E6 Operation not allowed with the current file openflags (maybe other causes too?).
0xC9204509 SDMC/NAND bus error, REG_SDSTATUS: TMIO_STAT_CMDTIMEOUT
0xC960454B SDMC/NAND bus error, when an error-bit in REG_SDSTATUS separate from the above errors is set. This can also indicate that the TWL partition table in the NAND sector0 is invalid, or that the sector signature for sector0 at offset 0x1FE is invalid?
0xC960454C SDMC/NAND bus error, REG_SDSTATUS: TMIO_STAT_STOPBIT_ERR
0xC960F401 SDMC/NAND bus error, REG_SDSTATUS: Bit23 (0x00800000)
0xD9004587 FSPXI: Hash verification failure (only for NCCH region hashes?).
0xD9004588 FSPXI/FSUSER: Verification failure for RSA or hashes. FSUSER: Verification failed for savegame AES-MAC.
0xD900458B Invalid RomFS / savedata block hash.
0xD9004676 FSUSER: The specified service-command / archive is not accessible, due to the currently used exheader accessinfo not having the required bit(s) set. (This error can also indicate that the required ARM9 access-control mount flag is not enabled, in the exheader for any of the running ARM11 processes)
0xE0C046F9 FSPXI: Specified read-size doesn't match the actual filesize, when accessing ExeFS.
0xE0E046BE Invalid lowpath. This can also indicate that the specified archive-id does not exist, or that the specified archive-id is not accessible over FSPXI. In certain cases this can also be caused by attempting to open a FSUSER archive where none of the required bit(s) for the archive are set in the user-process exheader accessinfo.
0xE0E046C1 File-reading returns this when the input 64bit file-pos is negative, or when the file-pos is larger than the filesize.
0xE0E046D1 Failed to write to file because it would exceed the file size limit of the file system.
0xE160F402 SDMC/NAND bus error, REG_SDSTATUS: TMIO_STAT_RXRDY
0xE160F403 SDMC/NAND bus error, REG_SDSTATUS: Bit28 (0x10000000)
0xE160F404 SDMC/NAND bus error, REG_SDSTATUS: Bit27 (0x08000000)
