Joshua Goins 9fa11ab760 Check entries that actually exist in slot roundtrip test
This doesn't fix it yet (because we're lacking some write capabilities)
but now it shouldn't assert before it even tries.

Ireko

Library for reading save files from 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.

$ ireko DollsNestDemo/Saved/SaveGames/AR0XJGFWA6HNIQ1AAUJ9UR828/Persistent.sav
Ok(
    TaggedSerialization {
        size_in_bytes: 135908,
        objs: [
            TaggedObject {
                size_in_bytes: 135904,
                entries: [
                    Entry {
                        name: "SavedDataVersion",
                        type: Some(
                            Int(
                                IntProperty {
                                    integer_size: 4,
                                    value: 0,
                                },
                            ),
                        ),
                    },
...

Technical Details

Dolls Nest uses the EasyMultiSave plugin, 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.
