Sonic the Hedgehog 1 for SegaCD is an open-source port of the Mega Drive version of Sonic the Hedgehog to the Sega CD console by HCKTROX.

Its main objective is to give a working example game for the Sega CD, and to let newbie hackers experiment and familiarize with the hardware.


  • Support for all regions.
  • Based on MarkeyJester's Two-Eight project, allowing 128x128-sized chunks to be used.
  • Includes examples of BRAM management (used to save the game features).
  • Little bugfixes to the original engine.

To Do

  • Implement PCM-sound playback system.
  • Implement FMV-video playback system.

How to use

Before using it, you'll need to compile the game first.

  • Go to source code's root folder -> Game -> BuildAllFiles.BAT. This will compile the files required for the disc image.
  • Go to root folder -> BuildISO.BAT. This will generate the playable ISO file.

(Note: Try copying the files to a shorter file path if doesn't work)
