Ha ha - thanks... 🙂
The maze collision routine would have to be completely re-written, as it doesn't work the way the arcade (or 7800 version for that matter) work. 😞 I'm not proficient enough in the 5200 to be able to do that.
When I did Hangly Man on the 5200 I had to make changes to the maze layout to fit in the framework of how the maze collision worked there.
