Recommended starting Pokemon

Squirtle's water attacks are not very effective on Misty's Pokemon. It will be destroyed while battling Electricity, Grass, and Poison types in the next three gyms. It would be average against Psychic types and does well against Fire types and will be fine in the last gym.

Bulbasaur will do well against Rock and Water types. It will also do fine with Electricity types, but will not do great with its own type and Poison. It would do well against Psychic and bad against Fire types. It does well in the eighth gym.

Charmander will not do very well with Rock or Water types. However, it will do well with Electricity and destroy Grass and Poison types. It does well with Psychic and average with Fire. It does not do very well in the last gym.

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.

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.

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.

Glitches

Catch Safari Zone Pokemon w/o Safari Balls

First go into the Safari Zone (SZ). Go into the area with the pokemon that you want(e.g. Scyther). After you're there, fly to Cinnibar Islands. Surf up & down the right coast, and eventually SZ pokemon will battle you there. If you need other SZ pokemon, just keep swimming up & down the coast. The effect of this glitch doesn't affect your saved game. If you get tired of swimming, don't get out of the water: instead, save right where you are. When you resume your journey, the SZ glitch will still be in effect. This glitch works with any area, not just the SZ.

Duplicate items

To get WELL 99 of an item, put the item you want duplicated in the sixth item slot. Make sure you have the Fly HM, then Fly to Viridian City. Talk to the old man that stopped you in the begining of the game( kind of to the north) When he asks if you are in a hurry, say no and watch him catch a weedle.

Then Fly to Cinnabar Island, and use the SURF HM. Surf along the right COAST, Not in the water, if you surf in the water it won't work.

Now, use SURF until you run into a Pokemon called ''M'', ''Missingno.'', Or a Pokemon over level 100 Once you see one of those, kill it or just simply run away. DON'T CATCH THE M OR MISSINGNO. AS IT WILL RUIN YOUR GAME!!!

When fighting a high level M if you have a slow pokemon and it attacks you are screwed, as it has a VERY high attack, you can beat him by simply using a quick attack.

after you win/run look at your sixth item it should look VERY weird with wird symbols and such, don't worry all it means is you have over 99 once you use it up alot it will stop using symbols and once the supply gets back to 99 it will show up as ''99''

Mew Glitch/Ditto Glitch

Make sure you never fought the Trainer Jr. on route 24 with the slowpokes. If you have than go to the part where I mention IF YOU HAVE FOUGHT TRAINER JR.

First off make sure you can find a trainer you can battle who is off screen (prefer the one trainer who is in the tall grass going down the path that takes you near the cave to get Mewtwo) and save your game right here. After saving walk in the direction of the trainer that would make him appear and also will let him spot you. As soon as you press the direction of which he appears press start and fly away to Cerulean City when done right the trainer will not spot you as you are paused and as soon as you fly away he will spot you but will not engage a fight. Your start button will no longer work now. Head towards where the Jr. Trainer is with the slowpokes and fight him BUT make sure he walks towards you if he doesn't walk towards you and you are right in front of him the game will freeze. Fight him then fly back to Cerulean City. Now walk up the bridge that would lead you back towards the guy you flew away from and about half way up the bridege your start menu will pop up cancel it out and Mew will appear. If you evaded away from a different trainer then the one I told you about you must go to where the trainer was and figure out yourself where to go so the start screen appears.

DITTO GLITCH
IF YOU HAVE FOUGHT TRAINER JR.
Oh well looks like no mew for you.... unless you do the ditto glitch.

THIS WILL NOT WORK AT ALL IF YOU HAVE FOUGHT EVERY TRAINER IN THE GAME!

First you need a Pokemon with a special stat of 21 that is the most hardest part. Then locate someone who is off screen and save the game here. Walk in the direction in which he will appear and spot you. As soon as you walk in that direction press start and fly away. You will know you did this right when he appears and instead of the trainer spotting you your pause screen pops up instead and when you fly away he will spot you. YOUR START SCREEN WILL NO LONGER WORK! Make sure the area you are flying to has trainers to fight. find anyone to fight and now go find a ditto. when you spot a ditto it is smart to have a Pokemon other than the one with the special stat of 21 to go out first instead so that way when you find a ditto you switch out the one for the special stat 21 pokemon. Ditto will transform into your Pokemon with 21 speical stat. Kill it. Then fly back to wherever you flew away from battle. when you are near the area of the evaded trainer your start menu will pop so close it and BAM! Mew.

Also I would look up the ditto glitch on google because you can get any Pokemon in this game without needing a red version or trading Pokemon for those who can only evolve through trading.

Costal Flooding

On Cycling Road, On the North-west side there are rows of trees. Go down so you only see water, and go back up. The trees have disappeared! Do this again and they will reappear. This does not affect your game at all.

Rare candy glitch

Use the missingno glitch to duplicate rare candies. You talk to an old man in veridian city and let him show you how to catch a Pokemon. That activates the glitch then you fly back to cinnabar island and go to the right and swim up and down the side of the island until you run into missingno or "M". DO NOT CATCH IT! it can crash your file. Use the items you want duped to be in the six slot in your item bag!
