A Shiny Celebi at level 93 obtained with the glitch.
The Shiny Celebi trick is an adaption of the bad clone glitch discovered by Paco81 for obtaining a stable Shiny Celebi in Pokémon Gold, Silver and Crystal, put together by gia and originally documented in a three-part 2009 video.
It allows the player to obtain a Shiny Celebi by using a Pokémon that has exactly 251 happiness, a "wall" (a Pokémon with 255 happiness to block corruptions beyond it) and a "donor" which will give specific DVs to the end result based on its species and held item (such as Growlithe; 3A holding a Polkadot Bow; AA).
This trick is an elaborate byte shift exploit, where depositing a Pokémon above the future Celebi causes data to shift up one byte.
1) Get bad clone ready in the storage box. To get one you should deposit more Pokémon than you have ever deposited in a box (and at least 5 or so), then change boxes and reset the game shortly after the Yes/No box disappears (Gold/Silver) or after SAVING... DON'T TURN OFF THE POWER. is fully printed (Crystal). Getting a bad clone is normally difficult but Pokémon Stadium 2's Game Boy Tower makes it a lot easier if you reset the game after the "Saving..." message appears at one of the aforementioned moments.
2) Catch Rattata ("CELEBI" or nickname you choose for Celebi) in Friend Ball.
3) Put "CELEBI" to sleep with Drowzee's Hypnosis on Route 34.
4) Give "CELEBI" 28 vitamins (e.g. 10 Protein, 10 Iron, 8 Carbos), a Heal Powder and three more vitamins to give it 251 happiness (should be done just before withdrawing over 7 Pokémon begins).
5) Catch another Pokémon in a Friend Ball for it to have 200 happiness and max out its happiness to 255 with 28 vitamins, call it "wall".
6) Catch a Growlithe and give it Polkadot Bow, call it "donor". (These are for the DVs 3A, AA; which enable Shininess).
7) Your Trainer ID must not have a FF value when converted into hexadecimal from decimal. You can convert it using Windows Calculator. Furthermore, there must be no Pokémon with DVs of Attack/Defense DVs or Speed/Special DVs of 15, 15 (hex:FF) or any other FF value.

Why the donor works for making a Pokémon Shiny
In Generation II a Pokémon's Shininess is determined by its DVs. The byte 3A in the donor means an Attack DV of 3 and a Defense DV of 10. The byte AA means Speed and Special DVs of 10. These DVs are that of a Shiny Pokémon (a Shiny must have 10 Defense, Speed and Special DVs as well as 2, 3, 6, 7, 10, 11, 14, or 15 Attack DVs). Hence for maximum DVs on the future Shiny Pokémon a Ho-Oh (hex: FA) holding a Polkadot Bow could theoretically be used as the donor instead.
