Alternate Pokemon Colors
Did you ever notice how some of the Pokémon that appear in Pokémon Stadium have different colors? The secret to the color variations lie in the names you give your Pokémon as well as your trainer ID number (assiged to you in Pokemon Blue, Red or Yellow, whenever you start a new game). While there are a few secret names that change only certain Pokemon's colors, there are a few naming tricks that result in different color variations. For example:
Use only lower caps (ie: poliwhirl)
Reverse the syllables (ie: DRILLBEE)
Abridge the names (ie: Pika)
Attack first
Immediately after you choose a move and you want to go first instead of the CPU, hold L and press A. Note: This trick only works about 50% of the time, mostly in the Pika Cup.
Avoid recoil damage
If you use an attack that you know will kill the opposing Pokémon, but will hit you with the recoil, make sure that your Pokémon has at least 20 HP left. Use the attack and you will not suffer the recoil damage.
Battle Mewtwo
To unlock a hidden 6-on-1 battle with Mewtwo, beat the Gym Leader Castle and get trophies in all 10 tournaments in the Stadium Mode. The map screen will now turn to a night scene and a bonus tournament will open up in which you battle against the psychic super-Pokemon, Mewtwo (#150). Once you beat Mewtwo, you unlock a new game mode.
Bonus Stickers
Once you have beaten both the R-1 mode (including Mewtwo) and the R-2 Mode (including Mewtwo), you are given a set of bonus stickers that you can access in the Gallery Mode. When you're on the Gallery main screen, press and hold L and R and move the Cursor to Print. If you keep the buttons pressed, the Print option will now change to Bonus. You will now have access to a set of 16 bonus "wallpaper" stickers from all the different modes that you can print out at "Snap" Stations.
ChronoMew
(Note: you have to catch Bulbasaur, Charmander, Squirtle, Pikachu, Omastar and Ninetales!) To get ChronoMew you have to pick Bulbasaur, Charmander, Squirtle, Pikachu, Omastar and Ninetales then at the battle screen press A, B, B, A, C-Left, C-Right then START. You should hear a mew's cry then gets lower then growls. It'll pause, press start to battle with your new ChronoMew. (WARNING!!! If you press any diffrent button to start the battle all data will be erased that is all.)
Easy Way To Win Pika Cup
You will need a Blue or Red Version and a Transfer Pack to do this.
Perform the Missingno trick and catch an ultra-high levelled Pok'emon. Something like a Snorlax or Golduck would be good.
Now use Rare Candies to Level that Pok'emon all the way up to Lv255. If you do not have enough Rare Candies, put them in spot 6 of your pack and perform the Missingno trick.
When it reaches Lv255, give it another Rare Candy. The Pok'emon should grow to Lv0. Now give it Rare Candies until it reaches a level accepted by Pika Cup.
You should now have a much better chance of winning Pika Cup!
Faster Game Speed
Beat the game on prime cup (master ball) and go to gb (game boy) tower and press C-Right or C-Left and a sticker will be there amd the game will go faster.
Game Shark codes without a Nintendo 64 Game Shark

GB Speed Upgrades
There are two secret speed upgrades to the GB Tower Game Boy emulator that let you play Pokemon Red, Blue and Yellow at much higher speeds:
Doduo Mode: Beat the Poké Cup. Once you have won all the Poké Cup tournaments, the GB Tower changes into Doduo GB Tower and a Doduo sticker appears on the Game Boy. The Doduo upgrade doubles the speed of the game play when playing the Game Boy game on your N64.
Dodrio Mode: Play the Game Boy games at hyper speed with this alternate speed settings. To get it, you need to beat the Prime Cup (after you have already beaten the Poké Cup). You can switch between the different GB Tower speed settings during gameplay by pressing C Right.
Get Amnesia Psyduck
Have you ever wondered how you can get the elusive Amnesia technique? Well, it's hidden deep in Pokemon Stadium. Unlocking it will take a while, but it's definitely worth it. You have to register ALL 151 Pokemon in the Hall of Fame. Whenever you beat a tournament (or Gym Leader Castle), your six Pokemon are entered into the Hall of Fame. It doesn't matter whether you use rental Pokemon or your own, but you can't have any gaps. Once you've filled it all up, you are awarded a free Psyduck bonus Pokemon that knows the Amnesia technique.
Get Pokemon for Game Boy game
Complete one of the Gyme Leader's Castles of the Elite Four of your rival to get one of the following random Pokémon that can be transferred back to your Game Boy Pokémon game:
Yes, it's true: Surfing Pikachu is hidden in Pokémon Stadium. To teach your Pikachu Surf (a technique it can normally not learn), you need to first unlock the R-2 (Round 2) mode. Then do the following:
Enter the R-2 Prime Cup's Master Ball division (you have to beat the first three divisions first). Assemble a team that contains a Pikachu that does not yet know Surf. You HAVE to use a Pikachu from your Game Boy game. You cannot unlock Surfing Pikachu using a Rental Pokémon. Do not register your team! Pick it directly from your Game Boy cartridge.
You now have to beat the Prime Cup's Master Ball division using a three-Pokémon team that always contains Pikachu. Pikachu has to be in every one of the eight battles. You are not allowed to use any continues. If you do, you won't get Surfing Pikachu.
Once you have fulfilled all the above conditions and beaten the cup, you are shown an award screen with Pikachu standing on a surfboard. From here on, Pikachu can use the Surf technique both in battle and during gameplay (Game Boy versions only). If you've got Pokémon Yellow, you can now also access the hidden Surfing Pikachu mini-game. Simply go to the small hut on the northern beach of Route 19.
Get Togepi
Get a Bulbasuar, and fight and win against Venusaur, Mewtwo, and Blastoise. After you have beaten them, go to Pokemon Lab and use the new item called Toge-Stone. Use it on Bulbasuar and you will have Togepi.
Kids Club Hyper mode
In one player mode with three CPU controlled opponents, successfully complete "Who's the best?" five consecutive times on the hard difficulty setting within one match. Hyper will be unlocked as a new difficulty setting for CPU controlled players.
Mew
Mew will become playable, as a "Rental" Pokémon, in the Round 2 version of the game. He can only be played in the Prime Cup tournament, Gym Leader's Castle, Free Battle, and Mewtwo Battle modes.
Mew in Prime Cup
This trick requires a Game Boy Game Shark and Pokémon Yellow. First start the game and enable the Game Shark code to catch Mew. Put in first in your line-up,, then save the game. Go to the Game Shark screen and enable the code for the first Pokémon in your line-up to be any desired Pokémon. Check your stats and it should display your selected Pokémon's picture, but with Mew's name and information. Save the game. Place the game in the transfer pack and go to the Pokémon Stadium building. When prompted to select Pokmon, choose the one that was Mew. When you start the match, The Pokémon will be Mew.
Missingno warning
Do not transfer Missingno to Pokemon Stadium. It will glitch the game and make it unplayable.
More Damage
When executing a fighting move, hold A when the description of the move is displayed.
New Title Screen

Real way to get Muk
Lots of people say that if you keep taking pictures of grimer in the cave level he will evolve into Muk.That doesnt work.(I wasted all my film there, and he STILL didn't evolve). Here is how you really get Muk. You have to take 1 picture of each of the grimer you see at the start of the level. After that you will see 2 grimers on ledges. Hit them with pester balls and he will evolve after you hit him 5 or 6 times.

The Stadium Cups:Hint
Raise your own pokemon on Red, Yellow, or Blue version so you will have better stats and you can custom your moves for the stadium cups.
Trade with out a second transfer pak
Put a box on the game, then put the Pokemon from a different game or the same one in the box. Then, go back to the lab and put the box back on the game that you are trading to, go to the box, and withdraw the Pokemon when you want or need it. Note: This also works with items.
Win Bonus Pokémon

Note that once you have beaten the Castle, you only need to defeat the Final Four and your Rival again if you want to win more Pokémon.
Here are the Pokémon you can win:
