I think scrolling has been done in a mode 4 game on the SAM.
Defender has a scrolling landscape and looks to be mode 4. I

Well things like Defender (I haven't seen the Sam version, but my
memory of the game is of large blocks of single colour) cheat by
only moving the edges. A bit like the old Snake game you get
now on Nokia phones - since the mid-sections aren't moving you
only need to draw the

Then a new version of Elite for the Sam would be really good, as
I'm sure that the framerate, resolution, colour, and/or
sound/music and maybe even a few other things could be improved.
I've heard that the BBC version works using a z-buffer, in thin
strips (due to memory
However it looks like hardware support for Z buffering will take
off, cos these days there are always millions of polys on screen at
once. Then the chances of obfuscation are pretty good, so the
gamble pays off.

I can imagine that would look horrible on a decent monitor,

This is true.
The buffering is worthwhile if you're likely to have anything else going
on in the same screen area which could corrupt the scrolled area (like
starfields etc)

The quickest way of accessing the dynamic tables for all this info
was by using the undocumented opcodes, because you start to run out
of registers otherwise - you can do INC HX (msb of IX) etc
