Summary0005918: Scrolling on AGA Machines is Jerky and fine on ECS Amigas
DescriptionThe Scrolling of this Game is pretty jerky on AGA Machines.
The Odd thing is; Scrolling from left to right is jerky but vise versa is butter smooth.

Very strange.

The game is flawless on OCS/ECS.

I tested the floppy and CD32 version. Same problem.

Jerky scrolling on AGA Amigas.

AGA amigas, you probably mean accelerated amigas? because chipmem access is often slow on high end 060 boards

I got this same issue playing recently on an 030-accelerated A1200, FWIW. But not sure if 030 accelerator also has the same issue.

Hi JODT \o/

The game runs great on faster amigas (OCS & ECS ; at least the ones i have tested)
but as soon as AGA is present, the screen scrolls pretty jerky.

Same happends with the original discs.

Maybe some blitter waits are needed for AGA ?

Anyway, greetings; Torti

Could you try the attached slave 1.2 ?

Scrolling should be ok on AGA machines now.
