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. Reason: Is this present in Japanese Stadium? This video is not available on Bulbapedia instead, you can watch the video on YouTube here. 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.
