Once, few years ago (and now while developing the wover game) i'v discovered an annoyance, while grabbing sprites, which were drawn on a hires image.


The x coordinate, while in hires screen, as you can test with the above code, is always at the even number.
That makes it difficult to cut out pixel perfect pictures.


the same is with y screen(y mouse) in laced mode.


this code is tested on amos pro v2.0 and easy amos.

Hardware limit:  sprite coordinates are low resolution on high resolution screens until AGA support is added.

thanks.


Edit:


Right, then the question comes up:


How does Deluxe paint do the painting in the Hires mode ?

The OS may have more resolution than the Amos hardware banging.
