The Rare Candy cheat, also known as the Old Man glitch, is probably one of the most infamous glitches in the Generation I Pokémon games. It is one of the effects of encountering Missingno.. It gives the trainer a very high quantity of whatever item is in the sixth slot of the bag (the most common item used for this would be the Rare Candy, hence the name).
It is a side effect of encountering Missingno. or 'M, where the amount of the sixth item in a player's bag, not necessarily a Rare Candy, is set to 128. By using all of these but one and repeating the bug, the player can have an infinite amount of that item.
As the trainer will often encounter Pokémon over level 100 that are hard to escape from while executing the glitch, it could be a good idea to clone Poké Dolls. If the player has a Pokémon in the party which is over level 100, a player can duplicate Rare Candies and repeatedly give Rare Candies to that Pokémon until the Pokémon reaches level 255, after which the Pokémon will level "up" to level 0.
As the Missingno. glitch was removed from Pokémon Yellow, the Rare Candy cheat is not possible in that version of the game.
Performing the glitch
Requirements
- A Pokémon that knows Fly (assuming the player has the badge to use it)
- A Pokémon that knows Surf (assuming the player has the badge to use it)
- At least one of the item to be cloned (for the purposes of this explanation, the article shall use a Rare Candy)
- At least five other items in the bag
- Access to Cinnabar Island or Fuchsia City
Instructions
- Talk to the Old Man located North of Viridian City. Allow him to demonstrate how to catch a Pokémon.
- Once he is finished, immediately Fly to Cinnabar Island or Fuchsia City and then Surf to Seafoam Islands.
- Make sure that the Rare Candy is in the sixth slot of the bag.
- Surf up and down along the east coast of either island where the water is touching the land. Whether Missingno. can be encountered depends on the player's name; other Pokémon may appear instead. Continue Surfing along the coast until Missingno. appears (assuming that the player's entered name will cause a Missingno. encounter). Some names may not cause Missingno. to appear. If so, the player may find 'M, which works just as well.
- Defeat, run from, or catch Missingno. or 'M.
After the battle, open the menu and view the items currently in the bag. If done correctly, the game should show "?8" or "?5" as the amount of Rare Candies in the bag (? being a glitch character).
The glitch can be done both with Rare Candies and with any other item. The most useful items to copy are arguably Master Balls, Rare Candies, Nuggets, expensive items such as Full Restores and Revives, or unique TMs. Key items, such as the Bicycle, can also be duplicated; however, it is very difficult to get rid of duplicated key items, as they cannot be sold or tossed, and can only be stored one at a time in the PC. Even Fossils and Old Ambers can be duplicated, potentially allowing a player to revive limitless quantities of Kabuto/Omanyte and Aerodactyl, which would not be able to happen again until Generation IV.
Cause of the glitch
Every Pokémon has a "Pokédex byte" that tells the game whether it has been seen or caught. A value of 0 means the Pokémon hasn't been seen or caught, 128 means it's been seen, and 255 means it's been caught.
Missingno.'s Pokédex byte is in the same location as the byte that stores how many of the 6th item is in the bag, as well as 'M's. This is why, when Missingno. or 'M is encountered, the sixth item slot is set to 128 (or 255 if it is captured). The glitchy box symbol is a result of the game attempting to display a number greater than 99, which causes it to grab sprites from beyond the number sprites. Sometimes it can appear to be a blank tile, but if one goes somewhere else or out of battle it will revert back to an unusual tile.
A way to tell whether " 9" is in fact 9 or [blank tile]9 is to select Toss. The quantity is displayed with a leading zero if the amount is actually 9, and as simply " 9" if not.
