Inno Setup was used to compile the .ISS to .EXE. The installer can be decompiled using
innounp.
Feel free to reach out through discord, we value clarity. This was a fun project, especially coding the GUI in python using PyQt5, I've never hated python more.
To use ChunkerDowngrader, run the installer, select the desired version and select your world folder. Here's an example as to what folder to select:
Code (Text):
- World <- Select this folder
|- data
|- playerdata
|- region
|- level.dat
|- level.dat_old
|- session.lock
|- uid.dat
