You can play Sonic 3, or Sonic & Knuckles but unfortunately you cant play Sonic 3 & Knuckles on Sonic's Ultimate Genesis Collection.
To return to the main menu in Sonic 3 and Knuckles for PC, you will have to go the settings tab where you see this option.
Yes,but on the sonic & knuckles side,not sonic 3 side
You don't. You need sonic 3 & knuckles to play as Knuckles.
Not on it's own, no. You can lock Sonic 3 onto Sonic and Knuckles and play as Knuckles through both games, though.
play sonic 3 once and sonic and knuckles twice
You have to unlock every Sonic & Knuckles lock-on individually by fulfilling specific requirements: Blue Sphere: Play Sonic the Hedgehog and Sonic 3D Blast 20 times each. Knuckles in Sonic 2: Play Sonic 2 and Sonic Spinball 20 times each. Sonic 3 & Knuckles: Play Sonic 3 and Sonic & Knuckles 20 times each. Note that you can simply enter and exit the game really quickly twenty times in order to fulfill these requirements.

Yes, it does! if you put Sonic 1 on it, it comes up with Blue Sphere the special stage in sonic and knuckles, If sonic 2 is in it, you can play as Knuckles in sonic 2 and reach places you couldn't with sonic!, but if you put sonic 3 in it it plays Sonic 3 and Knuckles and play sonic 3 as knuckles, acsess cheat code, but the final boss of sonic 3 is disabled as knux and Sonic 4 don't work cos that's for PS3 and Xbox 360 and wii
