→‎SetSdCardEncryptionSeed: info about private file value at offset 0x20

Line 1,118: Line 1,118:

Takes in the 0x10 byte SD card encryption seed, and loads it into FS-module state.

−

[[NS_Services|NS]]-module reads the 0x10 bytes from SdCard:/Nintendo/Contents/private, and compares them to the first 0x10 bytes of the ns_appman:/private (in [[Flash_Filesystem#System_Savegames|system savedata]] 0x8000000000000043). If they match, NS calls this command using bytes 0x10-0x20 from ns_appman:/private. The rest of this file (0x1F0 bytes total) is ~~(usually/always?)~~ all-zero ~~(however in some cases~~ the byte at offset 0x20 is ~~value 0x1)~~.

[[NS_Services|NS]]-module reads the 0x10 bytes from SdCard:/Nintendo/Contents/private, and compares them to the first 0x10 bytes of the ns_appman:/private (in [[Flash_Filesystem#System_Savegames|system savedata]] 0x8000000000000043). If they match, NS calls this command using bytes 0x10-0x20 from ns_appman:/private. The rest of this file (0x1F0 bytes total) is all-zero except for the byte at offset 0x20. This byte is set to 1 by NS if the SD card has been mounted successfully and is subsequently passed to SetSdCardAccessibility.
