Looks great, Rich is a real matter of all trades beeb and I think Archie related.

I like the sonar/ torch effect.
I've been working on timing the rendering of the torch to try and avoid tearing. I've mostly succeeded but more by trial and error than calculation.
I've been looking at SpritePlotterWithIRQ.txt which provides details that in mode 2 the CRT beam finishes rendering the screen 18.120ms after the VSync interrupt. From this I've been timing rendering using 18.120/256 as the time for the beam to render a memory line. This is making the assumption that there is no time delta between the Vsync interrupt and the CRT Beam rendering the top-left of the screen on the first line. Is this correct, or is there a known time delta that I can factor in?
