After over 5 years of release, and after the 10th anniversary of the original Sonic World, the source code for Sonic World Release 9 is available and installation is documented!

Everything should be there to get the code up and running, except for the assets, which you should pull from an existing release 9 download.

After the drama with the original creator, developers started to spin off using the then-abandoned code, eventually becoming what Sonic World DX came today.

We hope making this open source that it may cause new developments with this, may it be additions to the game, fixes of long-running issues from the years old code, etc.
