Somari on NES/Famicom - A game that never existed

Somari or Somari the Adventurer is an unlicensed port of Sega’s flagship Sega Mega Drive video game Sonic the Hedgehog for the Nintendo Famicom. It was released by Hummer Team in 1994. Somari is notorious not for featuring Sonic the Hedgehog as its starring character, but Nintendo’s mascot Mario, who in this game shares Sonic’s abilities.
