Note that you *can* change COLNO and ROWNO in order to produce a NetHack that generates larger levels than normal. However, it is bones- and save- incompatible in a way that is NOT detected properly and will crash your game; and the panning mechanism which lets you play ordinary 80x21 games on a smaller screen does not work, so you will need an actually larger screen.
