Wrong aspect ratio? #21

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. 10 CIRCLE 120, 87 ,87

What is the expected output? What do you see instead?
The on screen circle will look like a vertically stretched oval.

What version of the product are you using? On what operating system?
Latest public release.

Please provide any additional information below.
It might seem that right now, pixels are being rendered at 1:1 aspect ratio, 
which causes everything to look slimmer than it should.

I'd recommend trying the 10 CIRCLE 120, 87 ,87 "program" with a real Spectrum 
to see how the aspect ratio (and also the screen and border sizes, and the 
color palettes just in case) compare to the emulated ones.

Unfortunatly I do not have a real Spectrum anymore. I sold it many years ago to 
buy a Commodore 128 (big mistake).

Anyhow I remember that the circle was perfect. So this is an issue.

I see a related problem here might be that each emulated screen line from the 
Spectrum doesn't correspond with one of the real 625 TV lines, which is the 
size that should be implemented first, before stretching the screen 
horizontally to achieve the correct aspect ratio.

By the way, the so-called "double strike" video mode would work wonders here, 
if it could be implemented.
