Mapmaker 3.4 (successor of 2.0) now has support for maps greater than 8x12. This program lets you create xLIB tile maps and save them to matrices for use with xLIB. Some new functions were added, speed was increased, and user-friendliness was increased. Two example maps were added (one from the xLIB examples and a custom one) along with 2 tilesets (from xLIB and one I made).
