Nah. The 'l' was never supposed to be there, if you read his post a page or two up.
14 zones, 5 races, main title/invincible, menu, race results, 3 bonus stages, special stage, Knuckles' theme, 3 boss themes, Sonic 3 credits.
That should be everything. 31 total, but the bonus stages could be mixed into one track, and race results isn't exactly important (or nearly as catchy as its Sonic 2 counterpart).
This could be done, with better initial management than HH and a little cooldown time. Good luck to anyone crazy enough to try and pull one together.
