First, this is not my hack. It's a hack by Ice Man. But I've contributed some levels for the third world, so I thought it would be nice to give this hack a mention here. The hack was originally released in 2010, but Ice Man released an update for it in 2013 which fixes a few things, making the hack compatible on the real hardware as well.
