Crossplay

Is Sonic the Hedgehog crossplay?

Sonic the Hedgehog is only released on one platform, so there is nothing to cross-play with.

Sonic the Hedgehog (also know as Sonic 4) is an unlicensed game for the SNES by Peruvian scene organization Twin Eagles Group. It is, actually, a hack of Speedy Gonzales: Los Gatos Bandidos. Notable features include Sonic's new ability to kick, and missions to free Mario from cages (upon which the latter exclaims his name).
