| Archive | LowPath.Data format |
|---|---|
| (Shared)ExtSaveData(BOSS) | +0 u8 mediatype, +4 u64 ExtdataID |
| SystemSaveData | +0 u8 mediatype, +4 u32 savedataid |
| UserSaveDataForCheck | +0 u8 mediatype, +4 u64 savedataid |
SystemSaveData mediatype must always be NAND. UserSaveDataForCheck mediatype must not be NAND.
Mediatypes
| Type | Description |
|---|---|
| 0 | NAND |
| 1 | SD |
| 2 | Gamecard |
