Go outside the castle, near the waterfall. Climb the third tree from the waterfall. Do a handstand on top of the tree to get a one-up. Then, enter the castle's first floor. Now return outside and climb the same tree. Do another handstand for another one-up. Repeat this trick to collect an unlimited amount of lives.
In the "Vanish Cap Under The Moat" level, you can get three 1-up mushrooms on the first hill. You can then jump off the edge of the level and not lose a life. This trick gives you three lives in just a few seconds.
While in the Hazy Maze Cave, reach the Hazy Maze. Kill eight of the moles in a row to get a 1-up. Proceed to the single mole on the other side of the maze, kill him eight times, and get the 1-up. Then, return to the first pair of moles, kill eight in a row and the third 1-up mushroom will appear. Continue going between the moles to get as many extra lives as desired.Infinite lives (Japanese version)
During the first fight with Bowser, continuously avoid him and collect all the coins that appear. Continue to do this until 1,000 coins have been collected. Then, a green "M" will appear next to the number of lives remaining. From this point on, when a life is lost, the number of lives increases. While gaining lives will actually lower the number of lives remaining. The cheat will end if the number of lives reaches zero, such as when Yoshi gives Mario 100 lives after obtaining 120 stars. This trick cannot be done on the North American version as it only allows 999 coins to be collected. Note: Once the game is ended you will no longer have infinite lives.Triple Jump move and 100 life bonus
Collect all 120 stars, then go outside the castle. Climb inside the cannon opening that is now located where the grating was near the Fish Pond. Aim to land Mario onto the roof, where he will meet Yoshi. Then, Yoshi will speak to Mario, award a 100 life bonus and the Triple Jump move, and quickly leave.Warps

In the area with all of the mushrooms, you will see two tiny mushrooms that are next to each other. Jump to the second tiny mushroom to be warped to a hidden area below the mountain. From there, you can proceed to the cannon. You can also warp from the hidden area to the mushroom if you do not use the cannon.
Whomp's Fortress Warp: There is a warp in Whomp's Fortress that makes going up the fortress a lot easier. Proceed until you reach the area where a Thwomp is pounding the ground.
