Somari

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.

Somari is an attempt to bring the original Sonic the Hedgehog to the 8-bit Famicom. Mario (or “Somari”) can run and jump like Sonic, spinning into enemies, collecting rings and running around loops, with the spin dash technique included from Sonic the Hedgehog 2 for good measure. The game attempts to mimic the Mega Drive game as closely as possible, though its special stages are based on those found in the 8-bit version of the game (meaning there are no chaos emeralds), presumably due to hardware limitations. Scrap Brain Zone is also missing, though remnants of it exist in the ROM.
