# Ireko
|
||
|
|
|
||
|
|
Library for reading save files from [Dolls Nest](https://store.steampowered.com/app/1839430/Dolls_Nest/). Only the demo
|
||
|
|
is supported because that's what is available at the time of writing.
|
||
|
|
|
||
|
|
**The parser is not yet complete, and can only dump parts of the structured data. The code is also generally terrible because I'm still exploring the format.**
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Pass the `.sav` file you want to read as an argument. Not all `.sav` files are known to work, such as `Level.sav` and `Player.sav`.
|
||
|
|
|
||
|
|
```shell
|
||
|
|
$ ireko DollsNestDemo/Saved/SaveGames/AR0XJGFWA6HNIQ1AAUJ9UR828/Persistent.sav
|
||
|
|
Ok(
|
||

|

|
value: 0,
|
||
|
|
},
|
||
|
|
),
|
||
|
|
),
|
||
|
|
},
|
||
|
|
...
|
||
|
|
```

## Technical Details
|
||
|
|
|
||
|
|
Dolls Nest uses [the EasyMultiSave plugin](https://www.fab.com/listings/49f745a1-cbdd-4b18-8278-22ae1075d91d), which
|
||
|
|
saves using the `.sav` file extension. The save data is zlib-compressed, and decompressing them reveals a very similar
|
||
|
|
tagged structure to GVAS. See more
|
||
|
|
information [in this blog post](https://redstrate.com/blog/2025/02/reverse-engineering-dolls-nest-demo-saves/).
