Sonic 1 – Code Gray Game

"Sonic 1 – Code Gray" is a fascinating ROM hack that takes the classic Sonic the Hedgehog you know and love and gives it a moody, mysterious twist. Imagine blazing through Green Hill Zone—except now, the skies are stormy, the palette is eerily desaturated, and the whole world feels like it’s stuck in a glitchy, twilight state. It’s not just a visual overhaul, though; the level layouts are tweaked to keep even seasoned Sonic veterans on their toes, with new challenges and surprises lurking in familiar terrain.

This fan-made gem taps into that nostalgic Genesis magic while offering a fresh, almost dreamlike (or maybe nightmarish?) take on Sonic’s first adventure. If you’ve ever wondered what Sonic would look like in an alternate ‘90s dimension where everything got a little… off, this is your chance to find out. Perfect for retro fans craving something familiar yet strangely unsettling!
