Sonic 1 But Your Past Haunts You

By Selbi
 

(Or, Dark Rayman in Sonic 1)

The objective is simple: reach the end. Just make sure you remember where you were a few seconds ago, or else it will catch you.

The hack also comes with a few quality-of-life features to make the challenge more bearable, most notably infinite lives and replacing all shields and extra lives with invincibility, which also stack and tell you how much invincibility time remains. It also includes some general QoL improvements.

Backstory: Earlier in 2026, the first Rayman game hit its 30th anniversary and was celebrated with a fancy rerelease. While that version had some controversy (most notably the original music being replaced), it made me very nostalgic. Rayman on PS1 was definitely one of my childhood favorites, even though it was hard as balls. One of the gimmicks in the final few levels is Dark Rayman, an evil clone that copies all of Rayman's moves with a slight delay. Here's a video (starts at 0:51).

So yeah, I made a simple Sonic 1 hack that tries to recreate that gimmick. I have actually done a complete run of the game with live commentry a while ago, and it took me 1.5 hours to complete (with many F-bombs...), but at least I know it's possible without cheats.

Full Health Final Zone (Extra Download): This is the final boss with full HP (8 hits). In the main release, the boss only takes one hit to defeat because it seemed impossible to me otherwise. But who knows, maybe you can beat him fair and square!

This was an interesting challenge... but I got bored of playing it after 20 minutes. Marble Zone Act 3 was just too impossible for me to beat with that unskippable block section smh

"Dear Sonic, don't hate yourself, with love, Sonic"

This hack turned something as simple as GHZ2 into a infuriating hell. I punted at Marble Zone, I can't fight my past :D

This is a brilliant concept, as it forces me to think differently about how I play Sonic 1

I encountered a bug with Speed Shoes, where the tempo didn't revert back after dying with them on.

Also, might it be a good idea to use a different jump sound for "Previous Sonic"? I found it a bit distracting hearing multiple jump sounds.

Super interesting hack!
