Sonic Saves Mario
While Sega just recently released Sonic the Hedgehog 4 in late 2010, a Peruvian pirate game group beat them to it by 14 years. In 1996, the unlicensed programmers took the Super NES game “Speedy Gonzales: Los Gatos Bandidos,” inserted Sonic-themed graphics, and called the result “Sonic the Hedgehog 4.”
Amusingly, the pirate game sees Sonic rescuing numerous Marios (seen here) that have been caged up by an unknown entity. In reality, it seems likely that Sonic would have just raced past them without stopping.
