If the above video doesn’t look like anything new to you, that’s because it’s supposed to be an accurate homebrew demo of Sonic the Hedgehog 1 for the GBA.

Compare the clip to Sega’s own attempt in 2006 to port the game, and you’ll see why someone felt the need to try their own hand at it. Beyond the audio problems, Sega’s official game suffered from physics issues, screen stuttering, and an assortment of other snags.

The fan-made remake, created by programmer Stealth, seeks to amend all that and even features “the acceleration system from Sonic 2, the spindash technique, and two additional characters — Tails and Knuckles.”

The project’s current build so far only includes Green Hill Zone with all three of the characters, along with at a working special stage. No word yet on whether or not Stealth intends to add more to this proof of concept.
