See if you can get DOOM up and running on it.

Once that’s done, just upload it to your unit and hit the road. used KMZfactory, a free map editor for Garmin maps that goes the extra mile to split the tiles for you, keeping them under the 1MP limit. Then comes the fiddly part - rooting the map in reality by overlaying it on real roads using Google Earth. The map wanted to use was a huge PDF, so as a bonus, he shows how to get from PDF to JPEG in GIMP. Your map can be paper, PDF, or parchment it just has to be converted to JPEG.
