* Mario can keep a power-up in reserve like in Super Mario World (http://tasvideos.org/2307M.html) , and the change is immediately effective. * There is a new power-up, Magic Mario, which allows Mario to stomp on more enemies than otherwise possible, shoot extremely powerful projectiles, and take a few hits before losing the power-up. * Graphics are rendered with a custom palette. * Almost all levels end with a Boom-Boom battle. * There are 7 worlds which Mario can visit in any order, each containing a hidden key. * After finding all 7 keys and beating the 7 worlds, Mario can access the 8th world to beat Bowser and win the game.
