Super Sprite Generator issues
Re: Super Sprite Generator issues
There are a few (not all!) of those old QL MC games, which have a very smooth movement of their "sprites", even, if there are more than 10 on the screen. I wonder, how the programmers have managed that.

Re: Super Sprite Generator issues
Hi,
The other games with flicker free graphic sprites were accessing the screen directly and probably performing the write to the screen when the Raster Scan had passed.
The problem with Super Sprite Generator, is that the author did not use the correct Manager Trap to find the address of the System Variables and assumed they were at $28000.
This makes me think that the same assumption is made for the Screen base address.
But I have not got that far understanding the disassembly of SSG.
I am adding comments to the disassembly file, so that I should hopefully understand whats hoping.
