What it needs
Nothing. This conversion is built into Asteria, so it works the moment the app is open, even offline.
How it was tested
A real CUBE file was converted on macOS on Apple silicon and Linux, and the PNG that came out was opened and checked with ImageMagick identify to make sure it is what it says it is.
