It would be nice to import tilemaps so they can be used in Jo-Engine. Maybe .TMX format (tiled map editor) since this seems to be a popular one. The current MAP format of [filename], x position, y_position is ok, however converting to something like this that the saturn understands can be painful and time consuming if another map editor is out there that can be used. I think the purpose of jo-engine isnt to build a map editor, but provide an easy library to code on the saturn rather.
