Talk:List of Super Mario Bros. 2 glitches

Random Tiles Glitch
If anyone else has done this glitch or knows about it besides me, please put more info and clarify. I am writing this from memory of over a decade ago and don't have my NES or Super Mario Bros. 2 cartridge or NES Game Genie to perform this anymore. I can't remember exactly but I think only after the flap on my Game Genie was broken I was able to put the cartridge in at an angle. I'm not sure if this works for other games as well.

Glitches
There are many more glitches, off the top of my head:
 * If you pick an unripe vegetable (or certain other objects as Toad), at the correct frame upon exiting subspace, it will become stuck on your character sprite. You can climb vines and pick up other objects while it is attached to you, and you cannot discard it. It becomes "solid" when you change screens (door, climbing, falling, or dying) and usable thereafter as normal. This can allow you to take vegetables into fights with Birdo, or a potion to rooms without one (one interesting use of such is indoors in 6-1, where the unusable vases become warp zones, but only back to world 6-1).
 * If you push both up and down while climbing you accelerate upward quite fast. This is mostly only useful with a keyboard and emulator, or tool assistance.
 * Just before collision with an enemy, you can jump and then jump again in midair (a "doublejump").
 * Mushroom blocks can be placed inside almost any piece of semi-background scenery. It works better if you throw them into the edge (vines and chains are generally always one column, so both sides are edges).
 * POW blocks can make falling logs shoot straight upwards in some cases.
 * Throwing an enemy at another enemy you have just tossed, and having them collide before they both hit the ground, can shoot both of them straight up into the sky.
 * In some cases, you can throw a vegetable at an enemy you've already killed, and kill them again.
 * If you acquire a star, Phanto will avoid you, but if you pick 5 vegetables and get a clock to freeze time (on the 5th) while invulnerable, you can collide with Phanto to kill him. Note that some versions of SMB2 reportedly let you kill him with the key.
 * If you throw a potion above the top of the screen (such as in world 5-1, where you can get to) and go through the door, you will appear at the bottom of the screen in subspace, and immediately die.

As none of these seem likely to have been intentional (unlike tricks, such as picking a POW block in subspace and getting to keep it, bombs destroying miniture enemy-spawning vases, or reuse-recatch of vegetables) they probably qualify as glitches.
