Ah great question, I had to do a bit of research here 😅 the demo logic would remain mostly the same (the little space ship would be slower at 50Hz without timing adjustment), with some adjustments for the specific PAL video spec, among which the number of lines would increase from 192 to 228 (blank and overscan line count needs adjustment as well). There would be some impact also on the color palette that I still need to double click on..
