A glitch I came across, which I learned later luckytyphlosion did research on https://forums.glitchcity.info/index.php?topic=8379.msg209814#msg209814. In short, forcing the Game Corner text macro (0xF7) for the wrong NPCs allows you to purchase Pokémon you weren't intended to as if they were Game Corner prizes.
In addition to Pokémon Yellow, I believe this should also work for Red/Blue but with different requirements to the video. I may make a video of this glitch in Red/Blue in the future.

This glitch is another way to get glitch Pokémon with index numbers between 200-255 (but not all of those may be available) as well as 3TrainerPoké (00).

Arbitrary code execution to do this is arguably easier, but decided to document this for science and the fun of it.

Basic requirements for Pokémon Yellow:

1. Slots 1 through 16 should be Soda Pop x211 (you can use less slots, but there will be less NPCs who act as Game Corner prize vendors).
2. In slot 17, have TM47 (as the above redirects the texts to item 17, this tells the game to use the 0xF7 text macro (corresponding to TM47)).
3. In slot 18, have Escape Rope x211 (tells the game text pointers begin at the beginning of the items pack from slot 1).
4. In inventory slot 19, have a Coin Case. Preferably have many coins (stored item 53's quantity controls the first two digits, which if 0, you can toss 1 to get it as 255; giving a glitched amount of coins over 9999)
5. (See fixing your party and name to save the game)
6. In order to achieve 1-5, you will need to be able to perform the following glitches:

https://glitchcity.info/wiki/Trainer_escape_glitch#Ditto_trick  (for Z4)
https://glitchcity.info/wiki/Expanded_item_pack  (for the accessing items beyond the maximum intended slot for memory corruption)
https://glitchcity.info/wiki/Celadon_looping_map_trick (helps with getting the glitched items)
Item duplication e.g. from MissingNo.: https://www.youtube.com/watch?v=73fAlzIbi9k or https://glitchcity.info/wiki/CoolTrainer%E2%99%80 (with Ditto traded from Red/Blue corrupted with https://glitchcity.info/wiki/Swapping_Transform_moves_glitch  . You have to open the party menu before viewing -.)

(Exact positions and accuracy are important)

General procedure:

Swap the Escape Rope x211 into item 40 to corrupt the current map's text pointers. Talk to people and read signs, to bring up glitch Game Corner prize text boxes. These text boxes may corrupt your name, and sometimes you may have a very long name (infinitely long?) that prevents you from buying the Pokémon. Your party may also become corrupted.

Thankfully this only applies to a few of the text boxes, and often the glitch Pokémon will conveniently be sent to the Pokémon Storage System if you end up with over 5 Pokémon in the party.

Fixing your party and name to save the game:

Before performing this glitch, make sure you are in Cerulean City with the cop guard not blocking the way to the burgled house. Have two glitch Pokémon in the PC; one of them with Super Glitch as its first move (call it "party rdcr" or similar), and the other a Z4 (hex:C3) (called "fix name" or similar) with the following moves: Fury Attack, Horn Drill, Reflect, Super Glitch (learns Super Glitch at Level 35).

To avoid a game freeze, level that glitch Pokémon up with Rare Candies at the Celadon Pokémon Mansion safe spot; see https://glitchcity.info/wiki/File:Super_Glitch_safe_spot.png

1. Go to the PC in Cerulean City Pokémon Center, and go to withdraw the "party rdcr" Z4 but view its summary before doing so. If lucky, you will now have 0 Pokémon. Withdraw the Pokémon with the Withdraw box still up to get exactly 1 Pokémon. It's best to keep viewing its summary multiple times, as if you are unlucky and it doesn't work you'll have to do the entire glitch again as you can't be saving the game (without destroying your save file) until you fix your name.

2. Withdraw "name fix" Z4 and go to the following spot https://glitchcity.info/wiki/File:IFCG_spot_2.png . View name fix's summary multiple times to be safe, then walk back to the Pokémon Center to talk to the Pokémon Center nurse (may be important to avoid a glitch options box), cancel out and then save the game.

Congratulations! You can now use the glitch Pokémon you obtained with this glitch without breaking the save file.
