Multicarts

This one's from my own collection. It has the pirate version of Sonic 1, and a game called Street Smart.

Here's the cart. To change between the two games, you have to press reset.

Another one from my collection, with Sonic 1, JuJu (Toki), Quackshot and Castle of Illusion.

"1998 Super HiK 4 in 1" cart.

One of the games on 1998 Super HiK 4 in 1 is "Super Mario Sonik 2". You can play as either Sonic, Mario, Luigi or one of the Rescue Rangers. It's actually just an edited version of Rescue Rangers 2 (pictured right).

Super 12-in1 for the GameBoy Color, which includes the Sonic 3D Blast pirate game.

Image found on eBay. The cart has Sonic 2, Ghostbusters, and a couple of other games which I can't identify.
