The Gateway Command is a circular device that can link to other systems, similar to how a portal works. The difference is that a portal is only made of energy, while the Gateway is a mechanical device. In an effort to get to the Super Computer, Megabyte used Game energy to break into the Archives and steal the circuitry that runs a Gateway Command. He constructed the actual hardware himself, but had to have the circuitry board that operated the original device. His Gateway and the control circuitry were subsequently destroyed in a fight with Bob and Dot Matrix. (When Games Collide)
