Super Mario Bros 2: Mega Mario X
Super Mario Bros 2: Mega Mario X is an epic Super Mario World hack. It's setup like a Megaman game where you choose a boss from the main screen. There are a few levels to beat per boss. It features a neat item selection feature as well. If you collect 100 stars a item pop-up box will come up. Hit X to stop the scroll and X again to claim the item.
