No, theirs no other way to do that but to unlock S3&K
You can't.
play sonic 3 once and sonic and knuckles twice
knuckles in sonic two, blue sphere, sonic 3 and knuckles, flickey and ristar.
You can play them in the Sonic Mega Collection Games, but not in Sonic Gems:i can go super sonic says:but you need to unlock sonic 3 and knuckles that's what i had to do!
No, but sonic mega collection does. It's locked at first, so you have to unlock it. I would tell you how but I don't remember, sorry.
knuckles in sonic 2 :play sonic 2 and sonic spinball 30 times
sonic 1, sonic 2, sonic 3, sonic and knuckles, blue sphere, knuckles in sonic 2, sonic 3 and knuckles, sonic 3d blast, sonic spinball, dr. robotnik's mean bean machine, flicky, and ristar.
no. there is no debug mode in blue sphere and its pointless to have level select neather because the game is endless.
Sonic Mega Collection Plus is the same as Sonic Mega Collection except with additional unlockables.
Brace yourself. You have to enter Sonic 3 (You don't have to play it, just enter and exit it afterwards.) Do this 30 times, and do this with Sonic & Knuckles 30 times.
It is not on Sonic Mega Collection but it is on Sonic Gems Collection.
those are the sonic 3 levels play sonic 3 and knuckles level select you can to get it play sonic3 and sonic and knuckles 20 times each
