Does the hack actually have to be officially released or at least have an official demo? I would like for you to stream my collab hack,
SMW: Mario Edition.
It's just a beta, and you can walk across all paths. However, you may be able to walk on nonexistent paths and the game will crash because of this.
BETA
Pretty much World 1 has the only stuff available. World 2 doesn't have much. (You should use savestates because of impossible levels.)
