On sonic mega collection plus how do you unlock various sonic games

The games can be unlocked in two ways. The main way for unlocking them is to play a certain game or group of games a certain amount of times. This varies and is not specified, so the list is: Flicky- play Doctor Robotnik's Mean Bean Machine 30 times Ristar- play Blue Sphere, Knuckles in Sonic 2, Sonic 3 and Knuckles, and Flicky 30 times each. Blue sphere (lock-on game)- play Sonic the Hedgehog and Sonic 3d Blast- Flickies island 20 times each. Knuckles in Sonic 2 (lock-on game)- play Sonic the Hedgehog 2 ans Sonic Spinball 20 times each Sonic 3 and Knuckles (lock-on game)- play Sonic the Hedgehog 3 and Sonic and Knuckles 20 times each There are also two games (comix zone and the ooze) that can be unlocked either by having a save of Sonic Heroes at any stage in the game on the same memory card or by playing each mega drive/genesis game 50 times each. Note- by 'playing', you can just select the game, wait until you see the Sega logo and then quit. But to get the game, you must go back to the main menu. Then, go back to the games and you'll see the new one unlocked.
