If Bide deals damage to a Pokémon under Fly or Dig, the game will reveal its sprite early. The stored damage from Bide can hit (but not always) a Pokémon under the invulnerable stage of Fly or Dig. That movement alters the animations of the NPCs, disabling their animations. When the player walks, the screen moves the objects of the stage where player is, including NPCs. This video is not available on Bulbapedia instead, you can watch the video on YouTube here. Prior to Generation II, having the player character draw in a Pokémon battle causes the victory theme to play even though the player has lost. This prevents moves with 100% accuracy from missing, but does not affect the chance of hitting for moves with lower accuracy. In Pokémon Gold and Silver, if the move has 100% accuracy (after applying accuracy and evasion modifiers and the BrightPowder modifier), the move skips the rest of the accuracy check and hits. This prevents moves with 100% accuracy from missing, but also slightly increases the probability of lower accuracy moves of hitting. In Pokémon Stadium, the randomly generated integer is between 0 and 254 (inclusive). If a randomly generated integer between 0 and 255 (inclusive) is strictly less than the move's accuracy (after applying accuracy and evasion modifiers), the move hits however, if the random number is exactly 255, the random number cannot be less than the move's modified accuracy (regardless of its value).
The glitch occurs due to the accuracy check using a "strictly less than" comparison instead of a "less than or equal to" comparison.
Other moves also have 1/256 less accuracy than was intended. Moves with 100% accuracy have a 255/256 (~99.6%) chance of hitting (without accuracy nor evasion modifiers). In non-Japanese versions, Swift and Bide skip accuracy checks and always hit, regardless of this bug. In the Generation I handheld games, all moves are 1/256 more likely to miss than was intended, including 100% accuracy moves. If a damaging move's damage calculation yields 0 if it hits a Pokémon whose both types resist the move's type, the move will instead miss as if it were ineffective.Ī glitch similar to the Mew glitch that causes Route 6 to become glitched. NOTE: The following glitches affect all Game Boy versions of Pokémon Red and Green (1.0 and 1.1) and of Japanese Pokémon Yellow (1.0 to 1.3) unless noted otherwise.
