I'm making a video right now about testing several TMS9929A VDPs to identify fake ones. Would you mind if I include this project as one of the tests? I'll credit you both and the original author and I'll put a link to the Github page of course.

Also, how come these changes aren't in Github yet? The new code looks much cleaner.

Glad to hear you are interested,
Yes, you may spread the word and include the project, in fact, I started this tread, not only for myself but also to help others struggling with the same issues and interests.
And anyway, I believe we are all here at msx.org to help each other.

About, Github, we will publish it soon, and will update with the link.

Here's the video I released today testing TMS9929As I ordered from China. I used this Arduino tester as part of the tests (with a link to this thread and the Github repository in the description):
