Also known as: Super Mario USA (JP)

Super Mario Bros. 2, as it's known outside of Japan, is actually a Mario-ified version of a (not quite) completely unrelated game called Doki Doki Panic. Depending on who you ask, Nintendo thought the original version of Super Mario Bros. 2 was either too similar to Super Mario Bros., or too difficult for non-Japanese players to handle.
Fortunately, the game was a smash hit, and is considered by many to be superior to the "real" sequel. Many characters introduced in this game were quickly adopted into the official Mario universe.

Unused Graphics
Doki Doki Panic Leftovers
A few graphics from Doki Doki Panic can be found amongst the graphics used in the ending scenes.
A magic lamp. This item would later become the potion, and has the same effect.
This heart was the Doki Doki Panic equivalent to the mushrooms found in subspace.
A lock and a metal platform. These were used in the ending of Doki Doki Panic, and don't have any equivalent graphics/objects in SMB2.
Prototype Leftovers
These were used in the ending of the prototype. Instead of a display showing how many times each character was used, you received "prize money" based on how few times you died.
Miscellaneous Graphics
Hidden in the tileset for the desert stages is a little smiley face that isn't used anywhere, not even in the prototype. It appears to just be a placeholder.
Eighth Animation Frame
The animated tiles in the game (like the POW blocks and the cherries) actually have eight frames of animation. However, due to a bug, only the first seven frames are actually displayed.
Full Sub-Space Music
The music track used in Sub-Space is actually a bit longer than what you can normally hear. Under normal circumstances, the game boots you out of Sub-Space after about 7 seconds, which prevents you from hearing the full 14-second loop. The easiest way to hear it in-game is to pick up a Starman, enter Sub-Space, and then exit just before the invincibility wears off; if done correctly, the Sub-Space music will continue to play until the next track change. To hear the full song at the Title Screen, use the Game Genie code KEOOXXSE.
Unused Text
The string "ZELDA" can be found at ROM address 0x1FFFB. It appears that Nintendo copied the PRG footer/vector table from The Legend of Zelda (another FDS conversion) and simply forgot to change the title.
Version Differences
Fryguy Glitch

Normally, hitting a mini-Fryguy with a mushroom block will cause it to disappear in a puff of smoke. In the PRG0 version, however, if you manage to hit one while your character is shrinking, it will flip upside down and fall off the screen instead. This somehow confuses the game into thinking there are mini-Fryguys left even after the rest are extinguished, which causes the exit door not to appear. This game-breaking bug was fixed in the PRG1 version.
Regional Differences

Nintendo made the somewhat odd decision to release Super Mario Bros. 2 in Japan, under the somewhat odd title Super Mario USA, more than 4 years after its original US release. Aside from the new title screen, it is identical to the US PRG1 version.
