File Structure (Explorers of Sky)
Overview
| Offset | Length | Type | Name | Description | |
|---|---|---|---|---|---|
| 0x00 | 16 | SIR0 Header | A SIR0 header wrapping the item data. | ||
| 0x10 | (NbEntries * 16) | Item Data | A block containing entries for all items. | ||
| After Item Data | 3 | SIR0 Pointer Offset List | A list of encoded offsets to the pointers in the file. Since there are only the 2 pointers of the SIR0 header, those three bytes are always 0x04, 0x04, 0x00. | ||
| After SIR0 Pointer Offset List | 13 | Padding Bytes | Since all entries have a fixed size, and the SIR0 Pointer Offset List is 3 bytes long, 13 0xAA bytes are used as padding to align the end of the file on 16 bytes. |
