Format
There are three separate savegames, one for each Chapter, named BA.SAV, IF.SAV and UM.SAV
Each file holds 10 slots. And is composed by the Header and the slot sections. Positions are fixed. If you mess something up you can always delete the file; the game will always generate a default upon saving for the first time.
Each Chapter's slot is loaded in memory at different locations:
- BA DS:5491
- IF DS:557A
- UM DS:5663
The internal format is the following:
| Offset | Data type | Section name | Description |
|---|---|---|---|
| 0x00 | UINT16LE[2] | 2 Bytes Header | Incremental number, contains the latest slot number that increments upon each save |
| 0x02 | char[1700] | Savegame slots | There are 10 slots, 170 (0xAA) bytes each |
