| 0x567890B1 | Gamecard SaveData (for check). This is a wrapper for UserSaveDataForCheck: the OpenArchive code for that is called with archive-lowpath TID=0/mediatype=0. | Yes | No | No |
| 0x567890B2 | UserSaveData (for check). This is the same as the regular SaveData archive, except with this the savedata ID and mediatype is loaded from the input archive lowpath. | Yes | No | Yes |
Archives listed as not requiring a binary lowpath, use lowpath type empty.
Archives CTR NAND, NAND RO Write FS, TWL NAND, NAND W FS, and CARD SPI FS require the corresponding process exheader access control mount flag to be set, in the exheader for any of the currently running ARM11 processes, for FSPXI. The access rights checked by FS module for archive mounting with fs:USER, are stored in the process' exheader accessinfo.
The CARDSPI archive allows access to the gamecard CARD1 raw savedata flash(aka "cardspi:/" in Process9), the file lowpath must be WCHAR "/". The "NAND W FS" archive allows access to the raw NAND image(aka "wnand:/" in Process9), the file lowpath must be WCHAR "/".
