Pokémon Ruby Version, Sapphire Version, and Emerald Version - Fishing

Tags: pokemon-ruby-sapphire-and-emerald, in-depth-guides, fishing

The following process is used in Pokémon Ruby Version, Pokémon Sapphire Version, and Pokémon Emerald Version:

1. The game determines the number of fishing iterations, which is a random integer from 1 through X, where X is 1 for the Old Rod, 3 for the Good Rod, and 6 for the Super Rod. The game then waits 64 frames.
2. The game displays a text box and slowly displays a series of dots, waiting 20 frames before showing the next dot. The number of dots shown is a random integer from 1 through 10. If this is the first iteration, that number rises by 4 but not to more than 10. If the player presses the A button, the fishing attempt fails.
3. If this is the first iteration, the game now checks whether something was caught. If the first Pokémon in the player’s party isn’t an Egg and has Suction Cups or Sticky Hold and it’s Pokémon Emerald Version, the player will get a bite at a 57.5% chance. Otherwise, the player will get a bite at a 50% chance. A bite will never happen if there are no Pokémon that can be encountered at the location fished.
4. If the player gets a bite, the words "Oh! A bite!" are shown. The player must press the A button within the next 32 frames. Otherwise, the message "It got away..." is shown and the fishing attempt fails.
5. If there is only one fishing iteration, the fishing attempt continues at a 10% chance for the Good Rod, at a 30% chance for the Super Rod, and at a 0% chance for the Super Rod. If it continues, steps 2, 4, and 6 are repeated in a new fishing iteration. Otherwise, the fishing attempt succeeds and the player will encounter the fished Pokémon.
6. Otherwise, if there are still more fishing iterations, steps 2, 4, and 6 are repeated for each additional iteration. Otherwise, the fishing attempt succeeds and the player will encounter the fished Pokémon.

3. The game now checks whether something was caught. The player will get a bite at a 50% chance. A bite will never happen if there are no Pokémon that can be encountered at the location fished.
4. If the player gets a bite, the fishing attempt succeeds and the player will encounter the fished Pokémon.
