No need. We do stuff just for the sheer hell of it on here! :D

do you want a routine that you just initialise and it can scroll some text that you've entered somewhere?

If you want White ATTRs text on a Black background then I do have a routine already for that.

Can you clarify you want it to run in real-time, not pause frame-by-frame for use in stop-motion animations?

Joefish - erm - all the stop-motion is actually 3D animation done in Blender - so I'll be running it on an emulator and screen - recording. Sorry - this is all lies.

arkannoyed - that's exactly what I want - yes... What does ATTR mean?

Yes - that's exactly what I'm after!

I've not actually written the text yet... give me a week or so.

How hard is it to make such a big, pixel smooth scroll across the whole screen including border?
I think I saw such a scroll in some demo, but I cant remember it now.
It looks really impressive when text appears on one side of the screen and disappears into the other...

You can’t do pixel-smooth scrolling in the border area. The ULA is incapable of changing the color of individual pixels of the border; only 8–pixel-wide lines.

Does anyone know of examples of scrollers that make the best of this by using it as a 'stretch' scroll? Fat on entry including border, thins on screen, then fattens on exit left including border?

That is a whole different kettle of ULAs! It’s all to do with timing tricks, and will differ between all the machine variants, therefore also needs a model check routine too to adjust timings correctly. It does look nice though!

If you are looking for a generic routine to scroll messages outside screen then there's Rotatrix.

Proportional text looks a lot better. (Font is an old 42CPL one since I already had the sizes for the letters)

Yes, that's what I meant, it looks really great!
