Pokémon: Blue Version is part of the first generation of games within its famous series, known for having a very large number of beneficial glitches. In fact, the game can be completed in less than one minute of in-game time using save data corruption (as evidenced by this run), but this run avoids such techniques in favor of activating an entirely different glitch avoiding save data corruption.

This improvement from CasualPokePlayer skips the congratulatory speech from Professor Oak starting the Hall of Fame early.

You can watch the complete run played back on console.
