Pokémon Yellow TAS: Arbitrary Code Execution

HN points to it as the standard demonstration of arbitrary code execution on a Game Boy, and of glitches and bugs being turned into a working computer.

A tool-assisted speedrun of Pokemon Yellow by MrWint that uses arbitrary code execution to push Game Boy hardware to its limits. Through crafted inputs it injects code and ends up running other programs, such as Tetris, inside the game.
