Cheat/Tip/Shortcut: Here's a way to get a lot of HP on your Pokémon over L100. First you talk to the guy in VIRIDIAN that asks you stuff, you say no. Then you fly to CINNABAR and swim half water and half land. Catch a Pokémon over L100 and then do the RARE CANDY cheat but no need to go back to VIRIDIAN. Then raise it to level 255, then put it in Bill's PC then take it out again, then the level should be around L125 to 135. Do this cheat again if you want to have more HP on that Pokémon. The down thing is it must be over L100. This cheat should work since it worked for my friend and me.

Cheat/Tip/Shortcut: When I started out with BULBASAUR, and my name was Maximus, I went to VIRIDIAN CITY to talk to the man and then went to CINNABAR ISLAND and went up and down the coast, I found a level 180 CHARMELEON and a Level 160 Missingno whose appearance was of the bones of AERODACTYL. It was weird but I hope it helps.

Cheat/Tip/Shortcut: I was playing red when I used this code and I got SNORLAX at level 141, GOLBAT at level 128, and MISSINGNO at level 146. My starting Pokémon was CHARMANDER and the name I used was Ash which is 3 letters long.

Cheat/Tip/Shortcut: I can confirm the sayings [#2052] about MEW in the place where you can get EEVEE except you go in the front door and you can get MEW on the third floor from the guy who stands next to a computer after you get all 150 Pokémon. Hopes this helps!

Cheat/Tip/Shortcut: I have tried cheat #2015. It does work. It never fails.

Cheat/Tip/Shortcut: This is a variation of the MISSINGNO Cheat. I'll explain it as best I can. First put an ULTRA BALL in the sixth slot. Then fly to CINNABAR ISLAND, and TRADE a Pokémon. Then SURF where it's half water, half land. Then defeat MISSINGNO. Check your items, and you'll notice something different about the item that you put in the sixth slot: where it tells you how many of the item you have, there is a zero next to it (although you can still use the item) and a little flower that moves around. Stop SURFing. Go to the Pokémart in CINNABAR ISLAND. When the man asks you if you would like to buy or sell something, select sell. Then sell your ULTRA BALL, you know, the one with the graphic next to it, until it reaches zero again. Repeat this until the ULTRA BALL can't be seen in your item list. You should have tons of money!

Cheat/Tip/Shortcut: When you're in a city where there's a SAFARI ZONE try to get less than 500 bucks but not 0 then go inside and try to go in the SAFARI ZONE - the guy will say you can`t or something like that, try three times and now he will say ok only this one time, and he will let you in free.

Cheat/Tip/Shortcut: About cheat #2059. I tried it out on the Yellow Version. It doesn't work 100% of the time, but it does make Pokémon easier to catch.

Cheat/Tip/Shortcut: I will confirm some of the new codes you have gotten. In the first place I have Pokémon red version and there is a hidden REVIVE in the first statue next to the secret house in the SAFARI ZONE [see #2060]. Another thing is that I put my name as MISTY, and while doing the MISSINGNO cheat, I kept stumbling across level 147 STARMIEs. I have no idea if the Pokémon are supposed to be linked to the name you chose in the beginning of a new game, but I am testing more names. Another thing is after I did the MISSINGNO Cheat for RARE CANDY, I defeated the Elite Four. When I went to the Pokémon League site on the PC, I got a lot of jumbled letters and numbers, but the lucky half was that I got MEW's Pokédex information! This is not confirmed in my brother's blue version.

Cheat/Tip/Shortcut: I found a cheat for game boy yellow version, that there is a secret switch behind the drawing at the game center. From there you can get many items, so make sure you have enough places for the items. I have only found this secret switch in the yellow version. Is this cheat new? Have you been there before?

Cheat/Tip/Shortcut: I have tested Cheat #2004 and it does not work .....

Cheat/Tip/Shortcut: there is a house in CERULEAN CITY with a hidden RARE CANDY in the back yard of the house. It is the house closest to the water. It's in the northern part of the city. Go in the back yard and repeatedly press A.

Cheat/Tip/Shortcut: When you enter the Game Corner in CELADON, you should go down to the place where the 8 trees are; when you stand before the 4th tree on the right hand side, and you press A, you will find a PP UP. It will increase your Pokémon's attack (use it for your strongest attack). [The name I used was TATYANA and the Pokémon I used was PIKACHU in the yellow edition. I don't give my Pokémon any nicknames.]

Cheat/Tip/Shortcut: The phantom pc [see # 2015] in the corner of the CELADON hotel is in both red and blue, but not yellow. The MISSINGNO and level 100+ pokémon work on red and blue, but not yellow. I thought it would be useful.

Cheat/Tip/Shortcut: I'm writing about the cheat where you got from the SAFARI ZONE into Crazy Island (#2061), it worked on my yellow version, with the name TATYANA. My problem is I don't know what to do next, could you please try it out? You can't SURF because in fact you're really on cycling road (cycling is much more fun), I thought, I'll try to get on my BIKE (because you are just walking) but then it says "you can't get off your BIKE here" - PLEASE help me.

The only way to ever catch a MEW is with a GameShark.The code to catch MEW is 0115d8cf in blue and red versions. For yellow version it's 0115d7cf. You can get a GameShark at wal-mart or toys r us.

Cheat/Tip/Shortcut: Another way to beat BROCK in Yellow is to catch 6 PIDGEYs and train them. Use GUST or another attack. You might have to try it a couple of times.

Cheat/Tip/Shortcut: This works and I have done it and done it on some of my friends' games. In YELLOW, when you first get your PIKACHU, talk to him, he's not happy. Go to your house. Go into your PC. Push withdraw. And take out a potion. Talk to your mom and make sure that PIKACHU has FULL health. Then, try to give him the potion. It will say "it won't have any effect." Do it again. And again, and again, and once you have done it 20 times, talk to your PIKACHU. He will be HAPPY!! :-)

Cheat/Tip/Shortcut: You can't find MEW in Red, Blue, or Yellow(?). But I have one, by using Brainboy, made by Pelican Accessories. I have the red version.
