You just wrap the whole 80x25 screen into a form with fixed font and sufficient size to show it. You can actually define that form to use foxels instead of pixels, and give it .width=80 and .height=25 and there you are. Activate that form, and then run your FPD2.x app. I did that once during a lunch break, even added a background picture to the form. Looked nice... and DOSlike.
