This document was used hundreds of times to code the numerous fullscreen screens in the Vodka demo and afair, it never failed

In fact, it seems there is an "self-tuning" fullscreen routine at the beginning of the game (when screen is black) and that test fail on SainT.
You need to emulate opening the right border a second time. Which is what the calibration routine does, by mistake and not by design, instead of opening the left border.

In enchanted lands, what append on real hardware when "opening" right border a second time?
Opening right is done with frequency, and left with resolution. I don't endestand how it could be mixed/confused?
leonard wrote:a new line?? really? How many bytes is that line?
Hemm I'll to find my syncscroller table generator to compute a new one with a new line size, maybe I can get one scanline less !
It is possible to sync-scroll with one scan line less ... but not with this technique ... you'll need to wait a bit more to see how
leonard wrote:Are you working on a new syncscroll technic?
(I speak of a synscroll with every even adress boundary to do fullscreen scroll (non fullscreen scroll can use only 8bytes multiple adress).
By the "one less" than what? What is the record actually? I think ULM one is 5 raster lines. Do you think 4 is possible?
(I assume the "0 byte" line can't be used because it does not work on every shifters)
I understand that the current record is 6 lines, not 5. If I understand correctly, the ULM 5 lines scroller is for non-fullscreen only.
But, as you can test with a sync-croll table generator, using scans of zero bytes is not enough to hard-scroll with one scan less. You need something else
