At the title screen, press Up, Down, Left, Right, Y, X to unlock all levels.

Collect 50 rings, and finish the stage for there to be a giant ring entrance to the Special Zone.

You can almost always have the Special Zone entrance open (the giant ring next to the sign at the end of level Acts 1 and 2) by not losing your rings. If you do lose your rings, when you pass a checkpoint, intentionally die, then continue through the level without losing any rings. This works about 80% of the time.
