Battle leaders over and over again....
First you save in front of a PC and then you go and battle the Gym and its leader. When you finish, go and clone the pokemon that grew levels. When you turn your game back on you will be in the Pokemon center BEFORE you battled the leader but if you look in your PC you will find the Cloned Pokemon. Exchange the pokemon and save when you have your raised ones in your party then you can do it again.
Note: This trick will fill up your boxes so every three times you do this trick release the extra pokemon or switch boxes.

Beat the Game Early (Non-JP Versions)
This glitch will allow you to skip the end of the game, the "end" that is found after beating the game's boss atop Mt. Silver and obtaining all 16 Badges. Begin by obtaining a party in the early game (if possible) of your starter Pokemon, Kenya (the Spearow given by a man in a gatehouse in Goldenrod), the Togepi from the Egg in the early game or the Egg itself, and a Wooper. Teach Wooper Return and put it as its topmost move in the list. Make Wooper hold TM12 (Sweet Scent).
Next, rename Boxes 2-8 in Bill's PC, without the quotes. (Note that "@" means the accented "e" found in "Pokemon" and "#" the symbol for "male".) For Box 1, "BOX1". For Box 2, "AAAp@D95". For Box 3, "'v,'v@@72'l". For Box 4, "'v#@,2p". For Box 5, "@#2'v9@22". For Box 6, "'v8##4'v't'l". For Box 7, 'v@@@4p'l@". And for Box 8, "4@d2'd". Stand in front of the console at the bottom-left of the main Pokemon Center counter, open the Pokedex, listen to Bellsprout's cry, and use the Coin Case. Exit out of the menu and all the sprites should be invisible. Walk up the stairs to the Center's second floor and then down again to warp to Mt. Silver. Speak with the invisible Red there to automatically end the battle with him (as the game makes all battles a win when you have no Pokemon). And now the game is beaten!
Note that, after this glitch, you will have no Pokemon and no ability to catch them (as you will not be able to enter battles without instantly winning). This is rectified by obtaining a gift Pokemon, such as the Eevee from Bill in Goldenrod or the Shuckle in Cianwood.
Belly Drum Error
Belly Drum is a move who normally suffices to maximize the user's Attack to quadruple its normal value while simultaneously removing 50% of their current HP. Thus, the move is supposed to not function if at under 50% HP. However, you can still use Belly Drum: if you do so, the game will claim that it failed, but it actually did raise your Attack 2 stages (like x1.00 Attack to x2.00 Attack). This is because the command for Belly Drum is akin to 6 Swords Dances: however, one of the six routines is erroneously used prior to the HP deduction.
Bug-Catching Contest Pokemon Duplication (JP v1.0 Only)
This glitch allows you to copy Pokemon with the use of only one cartridge of a game. You will need six Pokemon for this, two of which are filler. In the second slot, you want the Pokemon of the desired species. In the sixth slot, you want the Pokemon of the desired nickname, gender, types, moveset, statistics, and IVs and EVs. (Thus, if the sixth Pokemon is Shiny, so shall be the resultant Pokemon.) The other four can be filler Pokemon, but be sure someone in the party can use Fly or Teleport.
Begin by putting the Fly/Teleport Pokemon in the first slot of the party. Now, deposit the third, fourth, fifth, and sixth Pokemon in your party into the PC. Enter the Bug-Catching Contest on Tuesday, Thursday, or Saturday per the in-game clock and go to the front of side exits when you are in the contest. When asked to quit, say "No" and then Fly or Teleport away. Put the second Pokemon in your party into the PC. Save and reset the console and then return to the National Park. Speak with the guard at the front or side entrances and opt to quit the contest.
After learning the results of the contest, you will receive a copy of the sixth Pokemon in the party, who is of the second Pokemon's species.
Drain Move Substitute Glitch *new*
In the Japanese releases of Pokemon Red, Blue, Green, and Yellow, as well as all versions of Pokemon Gold, Silver, and Crystal, there is a glitch involving Substitute - no matter the accuracy of the move, if it is a move that absorbs HP (e.g. Absorb, Giga Drain, Mega Drain), the move will have a 100% chance to miss!
NOTE: This requires at least two pokemon, and access to a PC.
First, take the pokemon you want to duplicate, put it into your group. Make sure you have a box with at least one free slot. Save your game in front of your PC. Then, go to the box, and deposit the pokemon. Exit the box, go to ''Change Box,'' select any box, and while it's saving, turn off the Gameboy.
NOTE: Make sure that you do it while the message ''Saving, do not turn off the power'' is still there. Otherwise it will not work.
Turn on the Gameboy, the box should be the one that you deposited the pokemon in. You should have the pokemon in your group and have the same pokemon in your group.

Easy Shiny Ditto/Mew
Note that this glitch involves the use of trading between Pokemon Red/Blue/Green/Yellow (R/B/G/Y) and Pokemon Gold/Silver/Crystal (G/S/C). It will easily result in a Ditto or Mew whose is Shiny, and thus automatically having above-average stats (as is the norm in Pokemon G/S/C). First, you must trade any Shiny Pokemon - a Pokemon whose color is different than normal - from Pokemon G/S/C to Pokemon R/B/G/Y. Any Shiny Pokemon will work, including the Shiny Gyarados you automatically find during gameplay. While on the latter, you need to find a Ditto in the wild: Mew will also work if you use other glitches in those games. While that battle occurs, have the Pokemon that was Shiny be in-battle until Ditto or Mew Transform into that Pokemon. Catch the Ditto or Mew thereafter. Once you do so, trade that Ditto or Mew to Pokemon G/S/C. In doing so, you'll figure out that the Pokemon was Shiny.
By capturing every Pokemon in the Kanto and Johto Pokedexes - aside from Mew and Celebi, which are optional - you will be able to speak with the Game Freak director in Celadon City to obtain a diploma recognizing this achievement.
Avoid random battles
When you walk up to the edge of grass use cut and the grass will be gone. No more random battles.

If you capture a Ditto you can use that for breeding. The Ditto will act as the female, so you wont have to get two of each type of Pokemon that you want the baby form of it. For Example just breed a Ditto and a Pikachu, and you will get a Pichu.
