Yellow - Cheats

Get Pikachu to like you sooner:

Start the game and go to the pc and get the potion. Next when Professor Oak gives a Pikachu to you, don't leave! Turn around and talk to Pikachu.(He will look sad.) Use the Potion on Pikachu. It will say you can't do it. But try it 5 times and when you talk to him again he will look very happy. Then leave by defeating Gary on the way out.

Celadon City Slot Tip
All of the slot machines have different odds, which change every time. Play each machine 4 times, and if it hits 2 or more, then stick with that one, because it's probably hot. If the slow machine forces you really close to a 777 or Bar Bar Bar it will probably give you one or the other soon.

Cut Down Grassy Areas
Once you get the HM "cut", your pokemon can cut down grassy areas. Use "cut" and it will cut a two by two area. Wild Pokemon will not attack you in the area you cut.

Easy Catch
When you are catching a pokemon. through the pokeball and press B and down at the same time(2 times),then press down untell you have your pokemon.

Easy Level Gain
To easily gain experience, simply switch the Pokemon you want to train with the top Pokemon on your list. When you go into battle the Pokemon will pop out. You can then switch to another Pokemon. Once you win the battle the beginning Pokémon and the fighting Pokemon will both gain experience points.

Extra Damage
While fighting, select your desired attack. When it says you are going to use that attack (eg. "Venusaur used Razor Leaf"), hold down the A button until your opponent's life stops draining. If your timing was right you'll do more damage than usual.

Cut the bushes and and go in. Keep fighting until you come across a Kadabra, then fight it and catch it. This could take a while but it is well worth it.

How to easily beat the Gym leaders
To beat Brock, catch a caterpie or metapod in Viridian Forest and evolve it into a Butterfree. Butterfree's confusion attack will work well.
To beat Misty, catch an Odish on route 24 (level 14 no less) and raise it on route 25. Also raise your Pikachu. Odish's absorb attack is super effective against Staru and Starmie as well as Pikachu's Thundershock.
To beat Lt.Surge, catch a Diglett/Dugtrio in Diglett's Cave and make sure it knows Dig, because it works great, but watch out for Riach Mega kick.
To beat Erica, evolve your Carmander into Charmeleon and she doesn't stand much of a chance.
To beat Sabrina, use that Diglett you caught hopefully it is now a Dugtrio, it's Dig is super effective. To beat Koga,use Butterfree's Confusion and Sleepowder and watch out for the powerful toxic attacks.
To beat Blain, evolve your Squirtle into a Blastoise and use water attacks. As for the quiz: #1 Yes #2 No #3 No #4 No #5 Yes #6 No.

How to get two HM's in Fushia City
If you are stumped on where to get the "surf" HM, Here's what you do. It's in Area 3 of the Safari Zone. You will have to get there fast as well. (I used a bike, I suggest you use it if you have it.) If you get into the secret hideaway in area 3, the man will give you the "Surf" HM. The gold teeth item is also in area 3. Give the gold teeth to the owner of the Safari zone and he will give you the "STRENGTH" HM. Use that to move the boulder and claim the item in the owners house.
