It was the easiest, and also very fast. The putchars routine appears to be optimized for displaying entire blocks of characters, and taking advantage of that would have required significant reworking of my display code (not to mention having to store a rendered version of the map, complete with colors... ugh). The other method described by LCD, namely changing just the first UDG every time I display a tile also promises to be slow, and more fiddly on top of that. But redefining the font was also fairly easy once I understood your tutorial, which laid the foundation for me. Thanks!
