Sonic 3C 0517 proto -

It has a credits, a working zone playlist and more. Sonic 3 complete is a category yet this is not. Its a midground between S3K and S3A too which makes it an interesting game to run.

Same can be said for S&K + S3 525 proto. Yet it just doesn't have credits.

Both of them are just S3K with S3A physics. Why are we not seeing a leaderboard for these two prototypes of S3K?
