Bugs:Pokémon Red and Blue
This page details bugs of Pokémon Red and Blue.
Due to an oversight, it is possible to create an unwinnable game in all versions of Red, Green, and Blue. Around halfway through the game, you are required to pay 500 Poké Dollars to enter the Safari Zone so you can find HM03 Surf and the Gold Teeth (to give to the Warden for HM04 Strength), both of which are required to progress further through the game. If you have no money at this point, have no items left to sell, have beaten all trainers accessible at this point, and have no Meowth that can use Pay Day, the game becomes unwinnable.
This was fixed in Yellow by allowing you to enter the Safari Zone with less than 500 Poké Dollars:
- If you have some money, you'll get less Safari Balls in relation to the amount you paid.
- If you have no money at all, bug the guard enough times and he'll let you in with one Safari Ball.
Man on the Roof Glitch
On Cinnabar Island, if the player doesn't have the Secret Key in the Bag and uses a Pokémon with Surf to surf on the east coast, returns to the shore while near the Gym and walks in front of the Gym's door, a sprite of an old man will appear on the roof of the Cinnabar Gym while the text box saying "The door is locked..." appears. After the text box disappears, the sprite will vanish.
There are other variations of this glitch, such as when pressing Start as soon as the player enters Nugget Bridge or Route 6. All variations were fixed in the European releases.
Escape Rope bug
In all versions of Red, Green, and Blue, you can use Escape Rope to escape the Pokémon Fan Club in Vermilion City as if it were a cave. This was patched in Yellow.
