Comment fait on pour gagner les jeux cachés

comme ca on est 2 a se poser la question moi aussi jaimerais savoir

Ben j´ai aps le jeu mais je crois avoir entendu qu´il fallait finir les jeux ^^ Bonne chance.

faut tous finir et pq bonne chance c hyper simple je trouve

chouette merci les gars

NGC4 déconecte toi je vais te rapeller

Faut il les finir avec tous les emeraudes car j´ai fini SONIC 3D et j´ai rien gagner.(je l´ai fini sans les emeraudes).

voila une bande de courageux. moi g fini les sonic sur emul, j´me suis moins pris la tete

allez voir sur le forum de sonic megacollection, vous aurez votre réponse.

Faut pas finir seulement les jeux.
Quand tu démarre un jeu, on t´affiche un message " Journal de la partie enregistré". Ce n´est que lorsqu´un certain nombre de messages comme c lui là sont apparus.
Bref, faut que tu démarres le jeu, que tu le quittes(j´ai bien dit quitté), et que tu redémarres les jeu.
C´est chiant, mais de cette façon, j´ai débloqué Sonic 3 et Knuckles.

Unlocking hidden games:
When you initiate Sonic The Hedgehog 1, 2, 3, Sonic And Knuckles, Sonic 3D blast, Dr. Robotnic´s Mean Bean Machine, or Sonic Spinball, the screen states that it is logging the game data. That indicates the game is logging in that you have initiated that game once. After initiating a game fifty times, it no longer shows that game-logging screen. It stops the logging sequence screen from ever starting a game again and from then on, just starts the Genesis program itself. To unlock a hidden game, you must start a particular Mega Collection game fifty times, continually pressing Z to exit it, then enter into the game repeatedly. Some hidden games do not necessarily require that you start up fifty times, but you eventually need to do so to unlock all the hidden games.
