Goldorak [ wip ] CPC version

[GUNHED]

As far as I know, smooth scrolling requires to have a split screen, because you need to compensate in one screen the lines you add to the other to keep the total amount constant. But if you know a simpler way to do it I would be happy to hear it.

What I would do for the most simple scrolling...
- in Y, set the number of scan lines per character to '2' instead of '8'. Put value 1 into CRTC Register 9 for this (it contains number of scan lines -1). This allows: Simple scroll in Y, 2 scan lines per scroll event (or more if you want).
- in X: Usual 2-pixel-wise = byte-wise scroll using CRTC Reg. 3

Being more close to a single pixel can be achieved by using different screens. Somewhere on my homepage is a racing game from a computer magazine (a type in), which is using pixel-precise scrolling.

Yeah, I think I'd forgotten some details like fiddling with R9 for part of the display at least. Like I said, it's been a long time since I played around with it 

That said, what I'd do is use the Plus SSCR, because it's way easier.

Going to write in a few minutes about the preview release.

Can I put the .CPR on my web site ? No problem if you prefer that it stays on official site and AmigaMuseum.
