How to duplicate items
Item duplication is when when you multiply items and you will get about 100+ of the items you duplicate. Just follow these step to duplicate items.
1.Have the item you want to duplicate on the 6th slot on your ITEM list.(Use select to move items)
2.Have a pokemon with fly and a pokemon with surf with you. Fly to Viridian and talk to man who tells you catch a weedle or whatever pokemon it is.
3.Fly directly to Cinnabar island and go left to the edge of the island.
4.Surf on the part of the water which is half-land. Do not go off this part where your surfing.
5.You will run into this wild pokemon called Missingo or M'. Do not catch it~!Either run away from it or defeat it.
6.The 6th item on your list now should have a wierd figure next to it. This means it has a 100+ of that item.
NOTE:Catching or seeing this pokemon (Missingo or M') will mess up your game and possibly delete it. If you dont catch it you should be good off. I am not responsible.
