Community Rules

  1. Site and Section specific rules apply!
  2. No simple file swaps. This includes swapping around files already present within CD's files.
  3. No recolor mods. Exceptions can be made if the mod changes a significant amount of other things outside of sprites.
  4. Only include files relevant to your mod. The game is able to fill in missing files if they are not a part of your mod.
  5. No basic physics mods. This means that you cannot simply make Sonic faster, jump higher, etc.
  6. Do not make or request very small music/sfx mods. This includes replacing very few songs/sfx, or something completely unrelated to the song/sfx you replaced.
  7. Random original character mods are not allowed unless the character has mass general public appeal and does not represent you as the submitter.
  8. Do not use content from other users' mods without explicit permission. Content that is used without permission is considered stolen and will be trashed.
  9. A mod.ini file is required in your mod, otherwise, it is liable to be withheld.

Sonic CD (2011) Banner

It’s time to usher the past into the future in this enhanced recreation of Sonic CD!
Sonic travels to the distant shores of Never Lake for the once-a-year appearance of Little Planet - a mysterious world where past, present, and future collide through the power of the Time Stones that lie hidden within it. 
Sonic arrives only to find the once beautiful world imprisoned beneath a twisted metallic shell. His arch-nemesis, Dr. Eggman, has come for the Time Stones and with them, will soon have the power to control time itself!
In order to put an end to Dr. Eggman’s nefarious schemes, Sonic must use the power of Little Planet to travel through time; breaking Dr. Eggman’s hold over the future by destroying his machines in the past and recovering the missing Time Stones!
Featuring 16:9 widescreen, achievements, leaderboards and both the US and Japanese soundtracks, experience the adventure through time that introduced the world to Amy the Hedgehog and Eggman’s most evil creation, Metal Sonic.
