Re: IIgs emulator with 1024x768 resolution

I can be done. You are going to have some problems though.

The quickdraw and several firmware routines hardcoded the resolution(s) and
the calc routines (in order to speed up execution).

You will need to patch GS/OS and any firmware the directly assumes that
640x400 (or 320x200) is the fixed video resolution.

There are many other issues as well. Maybe other folks can offer some
additional input here.
