System SaveData

Jump to navigation Jump to search

Savegames stored in NAND are located at nand:/data/<ID0>/sysdata/<SaveID-Low>/<SaveID-High>, where SaveID-High is the filename. SaveID-High is normally 00000000.

Access to system savedata via fs:USER is determined by the exheader_storageinfo accessinfo and systemsavedataid. Most ARM11 processes using fs:USER only have access to the SaveIDs specified by systemsavedataid, when a certain accessinfo bit is set the process can access all system-savedata however. The 8-byte systemsavedataid is two SaveID-Low words which the process has access to, normally only the first word is used. When the process doesn't have access to any system-savedata via systemsavedataid, systemsavedataid is all-zero.

NAND Savegames[edit]

The SaveID for system modules is usually 0x00010000 | uniqueID. The SaveID for other system processes (like applications) is 0x00020000 | uniqueID.
