I'm interested in knowing how Factorio reads the metadata for a saved game file.
In the Load Game GUI I see the following metadata:
- Map Version
- Scenario
- Difficulty
- Play time
- Mods
I unzipped a save game file and I have the following files, but couldn't find the data I wanted.
- control.lua
- info.json
- level.dat
- level-init.dat
- script.dat
