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 almost now complete (save for a few structs like DateTime), and write support is in progress.

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.

                                    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.
