Super Mario 64: The Green Comet is a hacked rom that was created by Arthurtilly. It is based on the original Mario 64 game and incorporates elements from Mario Galaxy 2, such as the requirement for Mario to replay all of the levels he has already completed but this time with new stars hidden throughout the levels.
Due to the fact that the game takes place after Mario 64, all of the castles and doors are open from the beginning of the game all the way to world 15. However, due to the fact that the game takes place after Mario 64, several elements, such as bosses, are absent from the stages because Mario has already defeated them.
