I am the proud owner of a Tufty 2040. It’s main.py file scans for py files and then lists them and lets you pick which one to run. That main.py file can be run on a Pico, Pico Lipo or Tiny etc. All it needs is modification for the display your using.
I did this on my Pico Display Pack. X is the up button and Y is the down button.
