Dusk: Scores File Explainer
This repo acts as a companion to my blog article Dusk: An Investigation Into Soap. It contains the Python script I used whilst trying to find where the game stored the progress towards the final achievement. I tracked changes with git whilst working through my experiments to help me explain the process retrospectively, and let readers have a look at the process in a more hands-on manner.
Note that the code in this repo is unpolished and not designed with any kind of "production" usage in mind.
Usage:
If you do want to try running the tool against your own Dusk scores file, then the only required dependency is python3.
Optionally, you may install termcolor, for some minor colour coding support in terminal output.
./score_record_splitter.py <path/to/scores>
Example output on a simple scores file (as of 52b54fc27 - note that once I'd learnt enough to finish my investigation, I did not then add my final discoveries of the purpose of the "middle chunk"):
$ ./score_record_splitter.py scores
