About this port

SMCraft is aksmith-git's from-scratch engine for Super Mario Maker 2 courses, with optional Super Mario Maker features including 100 Mario Challenge and costumes. Includes course tools and a self-hostable course server. Original artwork and sounds require data extracted from the owner's games; placeholder visuals are available. The separate recompilation component is a plan, not a working build.
