SEGA Genesis Classics

Load up the game and as you enter the first level 'Rookietown', there will be a chest right in front of you. Break it open with (B) and collect the 100 coins. Now enter the first door of the building right in front of you. It's here you'll be challenged to a game of Rock, Paper, Scissors for a cost of 50 coins. Accept and if you win, press and hold to rewind your game so that the match never took place and then press to fast forward so that you win again. Keep repeating until you have done this 49 more times.

If by chance you don't win, just rewind to the start of the match and hope that your 1/3 luck is in.
