oooh men that good memories brought me this post, I forgot to mention Mario 64, I could only pass it in its DS version, I remember the first xD boses even a small penguin that we had to rescue, I threw it into the void and I had to start the mission again, I think I passed in the full game when I was 13 years old in its DS version, the boss that I liked most was King Bomb although it was easy to win xD
