Dumping All Ini Settings Read By The Game
Entry posted by traison in Tech Support

1. Foreword
Since there seems to be quite a bit of confusion on the internet about which ini keys the game reads, here's a method for dumping all sections, keys and default values straight from the exe. It uses an x64dbg script to dump everything from the winapi calls. Data is filtered in a separate Python script. The setup is quite barebones, but it does the job.
2. Disclaimer
The results have not been verified, but at the time of writing I have no reason to believe this is incorrect.
3. Notes
- A key read is not a key used. This is not a list of ini settings that change something in the game. If the key you're looking for is not dumped by this tool then it absolutely won't work: a key that is never read, can never be used.
- Default values are the values passed to the winapi function, not what is in the default ini files. stepmodifications.org most likely has a different definition of defaults.
- GetPrivateProfileIntA internally uses GetPrivateProfileStringA. The game does not use the wide char variants.
