Install Sonic 3 & Knuckles Separately

Solution 1:

I have solved my issue. Silly me didn't look in the manual that came with AIR.

Here is what I did:

  1. Navigate to the AIR directory: %appdata%\Sonic3AIR
  2. Open settings.json
  3. Change "UseSoftwareRenderer" : false to true

After that it ran without any issues.
