The catalog in 3D

The same catalog has a room you can walk around in. The cat behind the counter is the AI Catbot, and they pick real games from it when you tell them what you feel like playing. Nothing is for sale, here or in there. Go in from here and this game is already out on the counter, with more like it waiting on the shelf next to it.

About

Sonic 1 Co-op is a ROM hack of the original 1991 game for the Sega Genesis. This modification completely overhauls the base engine to support local, split-screen cooperative gameplay, allowing a second player to join as either Tails or a duplicate Sonic.
