I didn't see that one coming trevormacro released the broken rom of the beta including a patch which fixes most of the broken parts to make it fully playable!

It's one of the most interesting SNES betas out there with plenty of differences to the retail game including different map designs, dungeon puzzles, tilesets, music, monsters and many other stuff! Source:
