Tnt has gm syntax, though I believe they coded it mostly in Java in Xcodes.
Hey Al, do you think it would be possible to recode Gm in Xcodes? Imagine, multi-window support, real mmorpg capabilities, a gui editor, many window size choices, super fast sprite movement, smaller file, less bugs, and unlimited sprites. Also, you could code in anything without limits, like a Z grid for a 3D engine, or anything else.
