Mew number 2 People dont know that there are 2 ways to get Mew, but there are. Dont fight any body in the 2nd gym. Defeat all the people on the bridge where you get the golden nugget, and then go to the guy standing near the middle of the bridge to the left of the one that you just got off of. Press start before you fight him, and fly or teleport to the poke center. Now, fight the 1st person in the 2nd gym. Your start button should work now, but dont save it, because it will skrew up the game. Walk up the bridge with the 5 people on it, the one that you get the nugget form, and in about 5 steps, your menu will pop up. Press B, and then you will fight a level 7 mew. It dies easy and only knows pound, so putting it to sleep and then poisening it is a good idea. It is easliy caught with a regular poke ball, but its health has to be low.
DO NOT fight the following trainers The Youngster with a Slowpoke (level 17) on the road to Bill's house(Route 25). He is the fourth trainer after you cross Nugget Bridge. The Gambler with 2 poliwags and a poliwhirl (all level 22) between Lavender Town and Saffron City (Route 8). He is standing just east of the entrance to Saffron City, facing north toward the door of the Underground Path. Make sure you have a pokemon that knows FLY. Make sure you have a level 5 or 6 pokemon and a pokemon that knows SLEEP on your team. Stock up with pokeballs. Now Save your game before you enter Route 8 since saving after this point will disrupt the procedure. On Route 8, stand in front of the door of the Underground Path (don't let the gambler see you or you will need to restart where you last saved). Walk down one step and IMMEDIATELY press start. If you succeed, the menu will pop up before the Gambler "sees" you. Go to the Pokemon list and fly to Cerulean City. The Gambler will see you just before you fly away. Your Start button will no longer function. Go north across Nugget Bridge and head east until you find the Youngster described above. If you walk right up to the Youngster, the game will lock up, so you will have to let him see you and walk up to you. Defeat his Slowpoke(afterwards your start button will work again), then fly to Lavender Town. Head west into Route 8. As soon as you enter the narrow path, the menu will pop up by itself. Press B to exit. . . and a wild Mew should appear. Mew will be at Level 7 and its only attack will be Pound. Once you've caught Mew, you can save without any ill effects
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. Chat 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''
Invisible pc In Celedon city, there is a hotel in the bottom right-hand corner of the city. In the hotel go to the northern-most portion on the right-hand side, take 2 steps back then one step up and you will be able to access the pc. 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 Veridian City, and chat to the old man. Have him show you how to catch a pokemon, then 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.
Get a diploma To get the diploma catch all 151 Pokemon and go and see Professor Oak in his lab. He will then give you the diploma.
Infinite Steps in Safari Zone This trick is very simple. Find a patch of grass in there. Stand in it and just tap the directional pad lightly just so you would turn without walking. You should encounter a pokemon and catch it if you would like.
ONLY way to get mew Restart your game and play until you get HM02 Fly from the house west of Celadon City (or just win the 3rd gym and get the badge that lets you use fly out of battle and trade pokemon that know fly to the new game).
Duplicate Pokemon You need a link cable, 2 pokemon games, and 2 gameboys for this trick. On 1 gameboy, have a strong pokemon that you both want. On the other, have a weak pokemon that your willing to give up for the other one. Enter Trade mode and trade pokemon. On gameboy 1 (the one with the good pokemon), turn off the gameboy right before it says ''Trade Complete!''. The 2nd GB should say ''Trade Complete!'' on it. If done correctly, the bad pokemon on GB 2 should be deleted and replaced with the good pokemon. The good pokemon on GB 1 should still be there.
Glitch City Glitch City is a weird glitchy town that you can unlock (and get to) by doing the following in this order: -Go to the Safari Zone (in Fuchia City) -Enter Safari Zone (pay the 500 bucks) -Go out of the Safari Zone and when the guy asks you if you want to leave, say ''No'' -Repeat the last step -Save your game when you are in the Safari Zone, and turn it off -Turn the game back on and leave the Safari Zone (the guy shouldn't ask you if you want to leave) -Go to Cinibar Island and surf half on land and half on water, DO this until a message pops up- ''PA-Ding-Dong, Time's Up! Your Safari game is over!'' - You will then be transported back to the Safari Zone -Exit the Safari Zone building and you will be in Glitch Town
