Infinite Lives For Mario!
Make SURE you have palyer 2 with you!
Blast to the SuperMassive Galaxy in world 4. Continue on your way as normal until you reach the Turtle Island. Once you're there, have player 2 freeze the nearest one so the turtles tail is twoards Mario. Have Mario jump on the frozen turtles back. (He will keep jumping.) While keeping the turtle frozen, wait until all of the turtles are in line behind the frozen one. Every time Mario jumps he will get a "1-UP!" Once he hits 99 lives he cant gain anymore, so hop off and return to the map with 99 lives!
Also if you have another save file, that palyer will recieve free 1-UPs by mail the next time they log on.
