I know dozens. My favorite ones is probably beating Super Mario 64 with 16 stars. First you need to get atleast have 15 stars and have access to the basement. Now go catch Mips the bunny that hops around in the basement. Now once you've caught him put him next to the door that leads to the door with the Key door. Mario should glitch through, now turn Mario around by crawling over to Mips. Grab him and drop him outside the door. Enter where he is and grab him. Place him infront of the 30 Star door and jump backwards. Mario will go through the door if you angled him right. Now just do the board Bowser's sub star, then do the 2nd Bowser. Go to the top floor. Now head to the star door that leads to the clock room. Backlong jump up the stairs and if you go enough speed you should go through the door. Now head to the endless stairs. Backlong jump up it again and enter the 3rd Bowser. Now just complete the game. Congrats you beat the game with 16 stars.
