Sonic 3 & Knuckles PC port: quick answers
- Do I need to own Sonic 3 & Knuckles?
- Yes. Sonic 3 A.I.R. needs game files from a copy you own. PlayPorted links only to the project page and never to game files.
- Is the Sonic 3 & Knuckles PC port finished?
- Yes, the project calls it playable, with no release so far.
- Which systems does it run on?
- Windows, macOS and Linux.
- Is it an emulator?
- No. Sonic 3 A.I.R. is a new engine that loads the original game's data, so no emulator is needed.
Maintain Sonic 3 A.I.R.?
