No, it IS in real Pokemon games and you DON'T need action replay. You can get there by tweaking.
In Pokemon, the game is separated by layers. An upper layer must have a lower layer beneath it. The Mystery Zone as well as much of Sinnoh is the upper layer of the Underground. It is not to hide an unused Dialga Sprite Glitch Pokemon, or anything like that. It serves as a upper layer for the Underground, as well as "filler" space between areas. Nintendo did not put a name for the Mystery zone, so the game displays "Mystery Zone" showing that it doesn't know exactly what it is. There was unused music for some routes, and it will play in the Mystery zone, because the game doesn't know which music to play, so it grabs an unused piece. So no. there are no Pokemon in the mystery zone. None at all.
its a place where you use your action replay to walk off the map until the location thing says "mystery zone".
Here it is, and to turn it on, press r and b. to turn off, press l and b.

Mystery Zone
when I did it ,it restarted my game.
sorry nothing you can do. new game it. same happened to me. your stuck.
Mystery Zone glitching allows you to get a legit pokemon using illegitimate means. You'd be using it to get to Flower Paradise, etc, without Oak's letter. The Shaymin itself will be the game's normal legitimate version that you would have obtained if you'd had Oak's letter, it will function correctly in every way.
on certain days activate the mystery gift and you may get an event
no you can't catch Pokemon in the mystery zone you can only catch Pokemon if you use action replay or r4 or whatever
u can with cheats
Mystery Zone
The mystery zone is a any place in the Pokemon game where you can`t go unless you have an action replay. Any place you normally can`t go in the Pokemon worl unless you have an action replay.
You need the cheat 'Walk Trough Everything' then if you walk further out of the real place you get in the Mystery Zone
the mystery zone is when u use an action replay and make ur character walk through walls
its only really named a mystery zone because your not suppose to be there
get a zigzagoon in safari zone
look at ur town map
when I did it ,it restarted my game.
In Pokemon the Mystery Zone is a location outside of the boundaries of the game world. This is normally inaccessible and can only be reach by cheating or exploiting a flaw in the game engine. Getting out of the Mystery Zone is harder than getting in as the menu is normally disabled here. The easiest way out of the Mystery Zone is turning off the game without saving and loading your save-file from when you were outside of the Mystery Zone.
to get to the mystery zone you need action replay and you need the code walk through walls.when you have those go to the trees and walk into them,kepp on walking and it will say mystery zone however it only works for Pokemon diamond, pearl and platinum.
