Here is a list of the id/descriptions. Where do they mount? (Like on windows the main partition is C:\ where it could be /dev/sda1, I would like a path like that for these) 0x00000003 Application RomFS 0x00000004 SaveData (the saveID/mediatype for this is loaded from data originally from the user process' exheader) 0x00000006 ExtSaveData 0x00000007 Shared ExtSaveData 0x00000008 SystemSaveData 0x00000009 SDMC 0x0000000A SDMC Write-Only 0x12345678 ExtSaveData for BOSS 0x12345679 CARD SPI FS 0x1234567B ExtSaveData, and ExtSaveData for BOSS 0x1234567C SystemSaveData 0x1234567D NAND RW 0x1234567E NAND RO 0x1234567F NAND RO Write FS 0x2345678A User/GameCard SaveData (for check), and other uses (FS can only mount the latter) (lo hi mediatype reserved) 0x2345678E SaveData, ExeFS, and RomFS (For fs:LDR, only ExeFS) 0x567890AB NAND CTR FS 0x567890AC TWL PHOTO 0x567890AE NAND TWL FS 0x567890AF NAND W FS 0x567890B1 Gamecard SaveData (for check). This is a wrapper for UserSaveDataForCheck: the OpenArchive code for that is called with archive-lowpath TID=0/mediatype=2(gamecard). 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.
