Hey, thanks a bunch! I could try something, any ideas how that would work?
This link shows some code page 437 compliant tilesets for Dwarf Fortress. I think it's just down to having a tile that matches to each of the glyphs in extended ASCII charset. That's what makes the charset so well suited to roguelikes; there's basically characters that can be used to represent all the entities, tiles, etc in a roguelike style game.
