Is it possible to use installed python with GUI?

Open gui_definition.json or batch files.
Then, replace all python\\python.exe with python, python3, etc.
You can remove the ./python folder if you installed python in your PC.
But I only tested with python3.10. It may not work with other versions.

At least, the tool will use the match-case statements.
It's a feature added at 3.10.

Change its width and height to power of 2.
Or use the no_mipmaps option.

And they require metadata editing if you want to change DXGI formats, resolutions, etc.
