Rerez talks about the smallest SNES game ever made which is the Space Invader. Space Invader is a popular arcade game back in early days, and the Nintendo GameBoy had their version. When Nintendo released their Super Nintendo Entertainment System (SNES), they create a Super Nintendo cartridge. With Super Nintendo cartridge, it allows players to play games which originally released for the GameBoy. For your information, original GameBoy only has a black and white screen. When using the Super Nintendo cartridge, it improves the sound and the color of the game. But if you have Space Invader GameBoy cartridge, you might get surprised because Nintendo had embedded the original Space Invader arcade version inside the small GameBoy cartridge. It is crazy and amazing!
