If you're talking about Super Mario 64 DS, then you need 80 stars to solve the mystery of the endless stairs.
In the Nintendo 64 version you need 70 stars. In the DS version you need 80 stars.
If you have an SM64DS level editor, place 3 different character doors in the top of the stairs, save, go up with mario, enter the LUIGI character door you placed, and try to find the Bowser in the sky hole because if you enter that door, the room become black. If you want to fix it, change the Luigi door's inside and outside area to 5
you need to clone 23 times and run in the stairs or BLJ into it!
first you need to play as Mario to do and you need 80 stars

I am elderly but not in a wheelchair. I need to know how many stairs are there to climb to reach the sistine chapel ceiling view?
2 stars
To fight Bowser for the last time you need 80 stars or 70 stars. To complete the game you need 120 stars.
Although there are 150 stars in total, you only need 80 stars (and Mario) to complete the game as this is the number of stars you need to get into the final Bowser level.
to get stairs in fsx you need to press shift+2+3
any number of stars with luigi or all 150 stars
