These cheats are cheats for the Gameboy, Gameboy pocket, and Gameboy Color. I am not sure if all of them work, but if you try hard enough I think they should. Some of them I cant get to work, but my friends have gotten them to work. The ones with a star beside them are ones that I have gotten to work and I think are really cool. I wont delay you anymore. Here are my codes!

Master Ball Cheat
When you throw a Great Ball, hold the up button and the B button simultaneously and the Great Ball will act as a Master Ball. Ive gotten it to, work, but this code only works 60% of the time so I dont like it a whole lot.
*Celadon Slot Tip

All of the slot machines have different odds, which change every time you visit Rockets Game Corner. Play each machine 4 times, and if you win 2 or more times then stick with that Machine because you will probably keep winning. If a machine forces you really close to a 777 or BAR BAR BAR then stick with it because sooner or later it will give you one or the other. I like this tip because, well, just because it almost always works.

Free Coins at the Game Corner
Walk around the game corner pressing A and you will find coins. I dont think this tip is so hot because it only works the first few times you visit the game corner.

*Ghost PC
Go to Celadon City and make your way to the Motel. Go over to the right wall, stand in the middle square and make Ash look north. Press A and Tah-dah! A Ghost computer! This isnt a really big deal but its pretty cool.

*Missingno, The 152ND Pokemon!
Go to Cinnabar Island and trade one of the guys in the Pokemon Lab. Then go to the Right coast of Cinnabar and surf up and down where it looks like you are half on land and half on water pressing a. Pretty soon you will run into a Pokemon that looks like a computer chip called Missingno. Hes level 80 so you should catch him. Some people say that if you catch Missingno your entire game will be erased but this has never happened to me. I love this code because it always works!

*Yuck! Rocks and Bait!
Was this your complaint when you entered the Safari Zone? I can help. Go to the Safari Zone. Waste all your time in a patch of grass where the Pokemon you want is. When the time runs out go to Cinnabar Island. Surf up and down the coast where it looks like you are half on land and half on water pressing A. It still works if you dont press A but its faster if you do. Pretty soon you will run into the Pokemon you want! And guess what else? No more rocks and bait! I like this code because it works.

*Fish in a Gym Hint
When you enter a gym go up to one of the statues. Get out a fishing rod and fish. This tip always works and you usually get good Pokemon.

Get a Togepi
First, defeat 3 of the 4 Elite Four. Save the game just before you fight Lance. Turn the game off. Turn it back on and defeat Lance and Gary. When the credits are over. Go inside your house and talk to your mom. Then go upstairs. Your mom will be lying on the bed. Talk to her and you will get a TOGEPI! I am not sure if this cheat works.

*Get High Level Pokemon
First, talk to the guy who shows you how to catch a Weedle. Watch him catch one and then immediately fly to Cinnabar Island. Surf along the right coast and you might run into level 135 Aerodactyls, level 135 Starmies, level 128 Hypnos and level 173 Rapidashes. Even more pokemon wait for you! This code always works and its pretty cool.
