Somari (音速瑪莉, Yīnsù Mǎlì),¹⁾ or Somari the Adventurer, refers to the unlicensed port of Sonic the Hedgehog to the Famicom, attributed to Hummer Team under the 'Somari Team' alias who supposedly trademarked the name “Somari” (森瑪麗, Sēnmǎlì) in 1994.

The game follows the usual Sonic the Hedgehog plot of Dr. Robotnik turning animals into robots, but with the obvious change of Sonic being replaced with Mario who can use the 'spin dash' introduced in Sonic the Hedgehog 2. However, the game suffers from bad programming as it's easy to die in Green Hill Zone, due to a lack of rings at the start and inescapable pits, only fixed or skipped in the Sonic-themed revisions.

While the game is mostly faithful to the original Sega Genesis game, Scrap Brain Zone was omitted and their Special Stage is borrowed from the 8-bit version due to obvious limitations. It only has one ending of Dr. Robotnik with the Chaos Emeralds, despite them not being obtainable because Special Stage was changed to a point-collecting minigame that doesn't even add lives or anything.

While the Hummer Team developers have published several revisions of Somari, the most common revisions in circulation are Somari and Sonic the Hedgehog. This has also led to an interesting phenomenon where unrelated developers have modified the game because it's so common. I've organized these into the following chart, to reduce clutter, with the more interesting revisions or hacks getting their own sections.

Speeding Hummer (超速悍馬, Chāosù Hànmǎ), also known as The Hummer, is a revision that changes the protagonist to Hummer Team's anthropomorphic horse mascot called 'The Hummer', and it is presumably based on the Sonic and Knuckles 5 revision. This revision can be seen in the Super New Year Cart 15-in-1 multicart, and most of the levels appear in the Samuri 60-in-1 plug-and-play console.

Jīqì(Robot) Māo(Cat) - Xiǎo(Little) Dīngdāng(Ding-Dong) (机器猫 小叮当), often called Doraemon,⁶⁾ is a unique Somari hack by Waixing that features Doraemon as the protagonist, along with completely new graphics, new level design, new music, but no special stage.⁷⁾ That being said, this hack is very difficult because of bad level design and cheap shots, though you won't lose 'all' your dorayaki if you have over 40, plus he can't drown.

Most of it is in Chinese, but you can probably figure out what 'Level 1, Act 1' (第一关一幕, Dìyīguān Yīmù) is supposed to say from context clues, though the final zone curiously says 'Level 6, Act 1' instead. After that, you'll get the basic credits screen featuring Doraemon, Nobita, and Suneo, with a list of everybody at Waixing that was supposedly involved with the hack, translated below:

• The level select code for Somari and most revisions is: ←, ↓, B, A, →, ↑, A, B, ↑, ↓, Start.
  • The level select code for Doraemon is: A, B, Select, ↑, ↓, ←, →, Start.
• Somari is in Season 1 Episode 11 of Novaya Realnost, but Suponev doesn't spend much time on it.⁸⁾
• If you haven't figured it out, Somari's sprite is derived from Super Mario Bros. 3.
• By the way, if you're interested in a ROM hack of Somari which completely overhauls the game and brings it closer to Sonic the Hedgehog, then check out Sonic the Hedgehog Vol. 2. This hack actually adds new options, new levels, new mechanics, new graphics, new music, the Konami Code, etc.
