Ever wondered what Sonic the Hedgehog would sound like if someone flipped the audio backwards? That's basically Sonic 1 Reversed Frequencies—a weird little ROM hack for the Sega Genesis where all the music and sound effects play in reverse. The gameplay's the same classic platforming you remember, but hearing Green Hill Zone's bouncy tunes turned into eerie, garbled noise is... an experience.

At first it just sounds like glitchy nonsense, but after a while your brain starts picking out familiar melodies in the chaos. The springs make this weird "sproing" noise when you hit them now, and Robotnik's laugh is straight-up unsettling. Honestly, it's more fun than it has any right to be.

If you've played the original Sonic to death, this is a fresh way to mess with your nostalgia. Just don't blame me if you start hearing reversed sound effects in your dreams.
