Thanks for this - it's likely legacy leftovers from my code iterations. When I started this I was new to VHDL so there are likely many more bits like this!...

Hi there - there is no schematic. The pins of the Z80 connected directly to the pins numbered as per the .ino code.

Came across this issue whilst digging through some previous notes I had whilst attempting non-blocking vsync. For what it's worth, whilst I used to work at AMD I cant remember...

Aha! Of course. I think this was an early version of FG in FSR3.0 where we explicitly used non-blocking vsync to reduce latency. It was removed in subsequent releases, fwiw....
