Hi @geab ,

It looks like that GitHub repository doesn’t have any substantial code. In the presentation he mentioned it uses a special version of MakeCode (around [https://youtu.be/LzkN4j2DB\_w?t=2032](https://youtu.be/LzkN4j2DB_w?t=2032)). The video is too blurry to see the URL.

I think the substantial part of Joshua’s work may be in another repo: [https://github.com/JoshuaAHill/Dissertation-Project-Files](https://github.com/JoshuaAHill/Dissertation-Project-Files), but that’s not a MakeCode extension.

It may be best to contact Joshua. Perhaps you can “Raise an Issue” on GitHub: [https://github.com/JoshuaAHill/dissertation-ui-example/issues](https://github.com/JoshuaAHill/dissertation-ui-example/issues) .

Bill
