*SONIC DEBUT* is a project I started on in early 2020, initially being a replica of the TTS demo, and evolving into a much bigger project. Recently, it's became increasingly obvious that the community's starting to get tired of Sonic 1 concept-related (aka "beta") hacks, and recently, I've also become quite tired of it.

After 2 years of development, I've rebooted the project for a more unique approach, based on Sega's arcade platformer titles. The Sonic 1 concept-based version of the hack is no longer in development.

Well, that's it for the introduction. Now, a description of the hack itself, at least in the status it was before it was rebooted.


This is a modification of Sonic 1 stylized within its earlier stages of development giving a unique twist on the game. Many prototype and concept materials are implemented here.
This hack features the following core changes:

  • Spinning Jump - Sonic doesn't instantly go into a ball when you jump. Press the action button mid-air to curl up and attack enemies.
  • Health System - Sonic's health is no longer tied to rings. In fact, rings don't exist in this hack! There is a more standardized hit system here, starting off with 5 hit points. You lose a life if you lose all your hit points. Extra HP monitors are scattered around the levels.
  • New Level Layouts - As per usual, there's a new level layout. Not exactly new, but rather a twist on the existing ones.
  • New Sonic Sprites - It's TTS! Now you see why we're changing that.

As I've stated before, this version is no longer in development, and many things are left unfinished. There may be many bugs and many incomplete things you may run into (such as everything outside Green Hill).
You can access everything else with the level select code U U U D D D R D L.

I hope you all enjoyed this twist on the game, and I hope for revealing the new arcade-inspired version of it soon.
