Thanks for the info, good to know, who was the original author and this is actually a rip.
@Walt: nice trick, played around with it in Vice, changing the values, now I see, how this works. Thanks! :-)

Just switching between 2 sets of coordinates every frame, which is why it flashes so much.

The 'stretch' is just setting $d017 to $ff before displaying the sprites and $00 during display.

In an emulator, try changing $08bf to $00 :)

Ripped of from Ratt Demo I.

As for stretch, didn't look too closely but isn't this just a split Y-expansion?

Sprite stretching from 1986!? :-O
The scroll and the stretching effect is quite smooth in overall, cool one.
