Missingno Pokemon:
The U.S. version of the game contains the following glitch Pokemon, which is obtained by using these steps. Go to Cinnabar Island. Enter into the building where the man makes Pokemon out of fossils. Enter the first room in the building with people that want to trade Pokemon. Trade with one of these people; it does not matter which one. Go back outside and move to the far right side of the building. Then, SURF up and down the side of the island while half on land and half in the water. Keep surfing until challenged by a glitch that resembles a microchip or barcode. He is part bird and part water type and starts on level 80. Note: Obtaining Missingno can keep the game from continuing correctly, including preventing linked battles, and other bad effects. It is recommended that Missingno be released unless you are just experimenting with the game.

Store the Missingno Pokemon in Bill's PC. It will eventually turn into a Rhydon.

Pokemon "M":
Go to Viridian City and talk to the old man. When he asks if you are in a hurry, answer "No". After he explains how to catch a Weedle, fly to Cinnabar Island. SURF on the side of Cinnabar that faces the Seafoam Islands to find the Pokemon "M". You may also find level 132 Mewtwos and Alakazams. Note: Obtaining M can keep the game from continuing correctly, including preventing linked battles, and other bad effects. It is recommended that M be released unless you are just experimenting with the game.

By using this trick, you also have a very rare chance of getting Mew.

Unlimited items:
Find the Missingno Pokemon and defeat him. A design will appear in your sixth item. Deposit your sixth item individually until it totals 99. Then you can divide the items by fifty. If a no more room message appears, just withdraw an item and keep depositing the sixth item. Check the CPU when this is complete to find two groups of 99 of the same item. Note: Obtaining Missingno can keep the game from continuing correctly, including preventing linked battles, and other bad effects. It is recommended that Missingno be released unless you are just experimenting with the game.

To get 99 of any item, first put the item to be multiplied in the sixth slot. Now use FLY and go to Viridian City. Talk to the old man almost all the way north of the town. When he asks if you are in a hurry, say no and watch him catch a weedle. After that, fly to Fuchsia city. Make your way south and, when you reach the water's edge, use SURF and go to Seafoam Island. After arriving, swim up and down the beach until you run into a Pokemon called "M" (a glitch like Missingno). Once you see him, kill him or run away -- do not catch him! After that, you should have 99 of your 6th item! Note: You can do this code as many times as you want and you can catch "M" another time. Additionally, instead of "M" a level 128 Starmie (Red Version) or Snorlax (Blue Version) may appear. Note: Obtaining "M" can keep the game from continuing correctly, including preventing linked battles, and other bad effects. It is recommended that Missingno be released unless you are just experimenting with the game.

Use the unlimited item trick with "Rare Candy". Once duplicated, use the "Rare Candys" on all your Pokemon that are at very low levels to quickly increase them. Note: The highest level possible is 100.

Instead of having to fly back to Viridian to do the trick over again (if duplicating more than one item), the items may be switched if you stay in the water.

Use the unlimited item trick after getting 1 Protein, Iron, Carbos, and Calcium at Go to Celadon city. Put Protein in the sixth spot, duplicate it, then repeat with Iron and the rest of the items. Use them on your Pokemon to pump them up.

When trying to catch rare Pokemon (Mewtwo, the Legendary Birds, etc.) use the unlimited items trick and duplicate the Masterball. You will never miss catching a Pokemon.

Unlimited money:
For unlimited money, place a gold nugget in the sixth item slot and get ninety-nine of them by using the "Unlimited items" trick. Sell all except one to increase your money. Use the remaining gold nugget to repeat this procedure. Go to any Pokemart and sell the nuggets until you have 999,999 coins. Go to Celadon City and go to the Game Corner. Go inside and talk to the man at the counter, who is on the right of the counter. He will ask you if you need coins. Say yes. He will give you 50 coins. Continue until you have about 7,000 coins. Now you can buy any item or Pokemon in the Prize Exchange house.

Using a Full Restore with the "Unlimited items" trick can also result in a large amount of money when sold.

Finding money:
Walk around and press A in the Rocket Game Corner to find coins that people have dropped.

Saving money:
Instead of repeatedly paying to get in the Safari Zone, save the game after entering. Then, instead of paying again, just turn off the Game Boy and turn it back on.
