You're welcome, I'm glad you're finding it useful.
I got a lot of requests for a Zero 1 image of my setup, and while I exclusively use my Zero 2W in my Pi Case, it seemed interesting (i.e., difficult) just from an embedded systems design standpoint so I decided to give it a go.
It was a challenging project but worth the results I was able to attain at the end: Neo Geo Pocket Color, of all things, was the most difficult system to get working full speed on the Zero 1's anemic hardware.
