All codes are from Pysduck's Pokemart.
Getting Missingno
To get MissingNo. go to Cinnabar Island and go into the Pokémon Research Labratory and trade with anyone in the first room. Then leave the Lab and go to the EAST of Cinnabar Island and surf up and down on the part where the land meets the water. Eventually the battle screen will come up and the screen goes black for about 5 seconds. Once you find him I suggest you use a Level 30 to 40 Pokemon. This is because Missing No., even at Lv. 80, has a VERY low defense rating. So get him down pretty low. Even at low he is still extremely difficult to catch. So next get a Pokemon that knows a sleep move and put him to sleep. Follow this up with a couple Ultra Balls and you should have him. Be careful, he has been known to erase games and since he doesn't go on the Pokedex don't bother getting him. Note from Zapdos: You will also fight M. The difference between M and Missingno is M evolves into Kangaston! Teach fly to M before you evolve it to get a weird Kangaston!
Cloneing
To begin, you must have two Gameboys linked. Gameboy A has the Pokemon to be cloned, and Gameboy B will have the Pokemon to be erased because they will get the cloned Pokemon (a weak Pokemon like Magikarp will do. They're easy to catch and worthless unless evolved). Gameboy A will be the first to enter the Cable Club, and the first to trade or this code will not work. Gameboy A will trade the good Pokemon, and Gameboy B will trade the bad one. After Gameboy A gets the bad Pokemon the screen will say "waiting". Gameboy A will turn off the Gameboy the second "waiting" clears off the screen. Then Gameboy B's screen will say "trade complete". The screen won't clear, so you'll have to turn the Gameboy off. Then, restart the game and you'll have a cloned Pokemon! The weak Pokemon will have disappeared because it never really traded (or didn't finish trading). NOTE: This may cause your saved game to screw up!
Land in water
To fight land Pokemon on water, go to the eastern side of Seafoam Islands. Surf up and down along the eastern coast to do that. The Pokemon that you fight are from the area you last visited. This even works with Safari Zone! Note from Zapdos: This also works at Cinnibar. And, if you surf against the land opasite of the patch of grass below Pallet, you'll be attacked by Pokemon from the grass.
The Daycare
Here is much experience your Pokemon can earn when they are at the Pokemon Daycare Center. For every step Ash makes, that Pokemon gets one experience point.
100+ Pokemon
Probably another glitch, but you can actually catch Pokemon that their Level is higher than 100! Here's how to do it: 1. Go to the Old Man, who blocked you off earlier in the game, in Viridian City. 2. Talk to him, and when he asks if you're in a hurry, say no. 3. Once he's done talking to you, Fly to Cinnabar Island without going to any places where you can fight Pokemon. 4. Surf up and down the right edge of the island, and when you enter a Pokemon fight, you can find a Pokemon whose Level is 100+! But you may not always find Pokemon with 100+ Level because this trick works sort of like the one at Seamfoam Islands. The stats of the Pokemon are like they would be at that level. For Golduck, which was at L152, all of his stats are 260+! NOTE: The major downside of this trick is that if the Pokemon gets any EXP (Even 1 point), its Level will go back down to L100 which can be good anyways. You can also find Missingno here, but he is even more glitched when you try to get him than with other codes. This trick works best if you use the Pokemon in the Cable Club since you can't gain any EXP when you fight a friend. This can also mess up your Pokemon Hall of Fame on the PC. Note from Zapdos: The highest you can raise one of these pokemon on rare candy is level 255
Duplicating
When you go into a battle with a MissingNo., the 6th Item in your "ITEM" menu will become maxed out. So, you can have 1 Master Ball in the 6th Item Slot, go into a battle with a MissingNo., and then you have 100+ Master Balls! You can do this unlimited times and sell the Items for major money! NOTE: This code will work regardless if you catch MissingNo. or not. Note from Zapdos: This Works with all TMs, items, and even the fossils for infanite tradible pokemon!!!!
Wall Walking
Using Gameshark type in 01a47ccf then go to a pokemart. It will be the first item in the list and will cost over A LOT of money. You know how to get infinite cash right? Of course you do! Now buy it and go to any 1 or 2 layer-thick wall. Then stand in the direct opposite of the direction of the wall. go to item, click on the new item you got. It should be called nickname. Note: Do not use it on a pokemon! Anyway, click on until you can use it or toss it. Then push b to get bak to the game, then you'll see ash and 3 pokemon in line.. on side of screen.. then push in the direction of the wall one space or two. Depending on how thick it is. Then push start, go to pokemon, get out and you are over the wall!!!!!!!! ~Thank Jedy567@aol.com for this code!
More Walls
Hey, you've found the HM06 code, walk through walls, I can help you out. I've had that code for a looong time and have found many secret stuff with it, no one else knows bout it! Here it goes:
Get back on S.S. Anne:(MED-HARD) Get in front of that guy who guarded that port for the SS Anne. Surf out one space to the right, then step left one. You should be facing left, yet one space above the guy. Use HM06 through the guy and walk down. Presto! The SS Anne never left!
New reaction to fishing:(EASY) First do the "Get back on S.S. Anne" trick. Go to the place where you can see out into the water. Get on one of the barriers and cast out your rod. It can be Old, Good, or Super. Wow! I never knew they programmed that into the game!
Beat Elite Four with only 1 LVL5 Magikarp:(MED-HARD) Basically you use it to go on top of the doors in the first three, then just push up. Lance is harder though. You must do it two spaces up, to the statue on his left. Strut past Gary (He doesn't fight you if you miss a person) and walk into the next room. Presto! Amaze your friends with it!
Secret Patch of grass and door that leads to nowhere:(MED) Go down from Pewter city to the back entrance of Viridian Forest. Don't enter the building, instead go southwest and use HM06 to go below the building. Try entering the lower door. What? Doesn't go anywhere? Go down now. There are two patches of grass where only I have been able to catch Pidgeys, Rattatas, and Weedles, though.
Walk in Bike Route:(EASY) Simple. Go to the house where you get HM05 and go down, and use HM06. Not that secret.
Get into Safari Zone for free with unlimited steps and balls:(HARD) Okay, now you should be able to do a trick where you can change ways you face without moving that way. It sounds confusing, but it's required. Now normally that guy stops you, but first go through the barrier on the left. Go up until the guy is to your right, and use HM06 to get on the counter, but not over. Now here's where the trick mentioned before is required. Do it so your side is facing up. Now use HM06 up one space. Presto! You're past that guy who stops you! You have unlimited Safari Balls and Unlimited steps in it! Problem is, you have to manually find your way out.
Pokeballs on top of nothing:(EASY) Go through the barrier so you are next to a Nurse Jenny. Talk to her and when the pokeballs are supposed to appear on that healing thing, they don't! Just interesting. You can also go behind the Cable Lady to find the stairs go to nowhere... ~animorph1000@hotmail.com
