The rivalry between Sega and Nintendo meant Sonic never officially graced the Super Nintendo (SNES) during the 90s. However, the pirate market filled the void with distinct bootlegs. The most notable is 'Sonic the Hedgehog 4' on SNES, which is actually a hack of 'Speedy Gonzales: Los Gatos Bandidos'. These games offer a bizarre alternate reality for collectors and retro enthusiasts, blending Sonic sprites with Nintendo-style platforming mechanics.
