you go down in the old wooden door in the castle once you defeated bowser the first time a door will unlock go in it, go strait then go right then go left you will see a wall go in it and... POW you did it.
Of course not, it's called Mario 64 because you play as Sonic.
If you mean that door in the rec room in Super Mario 64 DS with the number 8 on it, you just need to get 8 stars and then it will open. The course with Goomboss, who holds the key to the room where Mario is locked, is behind this door.
Get 8 stars,go to the room with the number 8 on it,jump in the Mario painting,defeat Goomboss.
You need to win it of course
of course not it's a nintendo game.
For the classic Nintendo 64: Just stand at the sun on the floor and look at the top of the light, you'll warp into the secret switch course. For Mario 64 DS version: Do the same as in the normal version for N64, you just have to be Mario.
what one Mario 64 ds or Mario 64 nes
Yes, Mario Kart 64 is for the Nintendo 64
No,it is impossible to get Waluigi in Super Mario 64 and Super Mario 64 DS.
Of course not! My friend got all 150 stars but not him.
To get the Wing Cap in SUPER MARIO 64 DS.Hit the red "!" switch in the Wing Cap course. A light will appear in the castle's main room once you earn enough stars, stand in the middle and look up to enter this course.
There are no power flowers in Super Mario 64. However, I do not if they exist in Super Mario 64 DS.
