Bortreb created a TAS (Tool Assisted Superplay) of Pokemon Yellow. What's unusual about this TAS is that the goal isn't to beat the game, but instead to send a program to the Gameboy and have it execute that program.

Basically, 10 minutes of gameplay is spent setting up RAM, then the game eventually jumps to the corrupted RAM, and executes a bootloader that reads joystick input into RAM, then executes that.
Finally, it plays a bad MIDI of My Little Pony Friendship is magic and displays a picture of balloons.
