Pokémon Gold and Silver form the second generation of Pokémon, after Pokémon Red and Blue. The main differences between the generations is that the game is now in full color, and that there are 251 Pokémon instead of 151.
CasualPokePlayer employs a staggering amount of luck manipulation and extremely careful routing (accomplished using the RouteTwo program) in order to improve upon the previous movie by 35.50 seconds. Only a few Pokémon are collected in this run, but all gym badges are acquired before defeating the protagonist of the previous generation of Pokémon games.
