I guess I probably should have explained in my initial post what I meant by "manikus' 800x600", but part of that was to see if anyone had been paying attention.
I do mean the larger (relative to resolution) square viewport.
I would like some further explanation on why the 640x480 is a good starting point for FRUAites. Please.
As for a square viewport for 640, that's doable, but a larger one...doable, but not as easy as what I did for 800x600. For my efforts, I took the viewport from the next size up, chopped off the bottom to make it square and went from there. But, the 800x600 viewport in 640x480 doesn't leave enough room for display of the party names and stats because even though CocoaSpud added an end of line feature, it never worked properly for making them small enough. I wanted to use the other viewport width because all of the wall stuff was already figured out. It is completely possible to put in any size viewport you want (within reason). I'll try and look at this again i the new version of DC.
If needed, Paul could probably help.
