Raster detection in assembly

[hellboy73]

Hi
Once I finally succeed in building my Minimal64x4 I would like to learn assembly and try to code a simple game maybe.
However I cannot find any information on how to detect on which scanline the code is running. Is there any way of finding out when Minimal is starting to draw a screen to have a silky smooth animation?

On the Minimal 64x4 software side there is no means of detecting the current scanline, i.e. to read out the hardware timer of the VGA circuit. This would require additional memory mapping circuitry which -- as you might imagine -- is not considered "minimal". This feature however could easily be added by an extension card.

Sure, i get it :)
So i will have to try minimizing jitter by timing the code carefully.
Thanks
