Re: [hatari-devel] aspect ratio problems

[Douglas Little <doug694@xxxxxxxxxxxxxx>]

Hi, thanks for the info.

The registers which cause this on Falcon are $FFFF82A8, $FFFF82AA.

I'll try with --aspect off to see if it helps.

To debug this, you can add some prints to:
         src/falcon/hostscreen.c::HostScreen_setWindowSize()

To see what sized screen is requested by Falcon registers and to
what size it's scaled.

You can also try "--trace videl" to see what register values
are set to Videl, and enable extra debugging from src/resolution.c.
