on top of the castle

On top of the hill. After Princess Peach sends Mario the same note as the original Super Mario 64. :)
You can't.
yoshi is at the top of the castle along with three 1up mushrooms and a wing cap block.
To get to the top of the castle on Super Mario 64, there are two ways. The first is to get a running start (running towards the right side corner of the castle), jump on the castle wall, then on the grass, then back on to nearly grab onto the edge, and get on top of the castle. The second way is to get all of the stars, then a cannon will be accessible out on the front part of the castle. Then, climb into the cannon and shoot yourself on top of the castle.
Yoshi is on the castle roof in Super Mario 64. Three lives and a flying cap box are also up there.
You use the moon jump cheat.
You can use the cannon to shoot up to the top of the castle. Yoshi is there in the Nintendo 64 version. After you talk to him, you will have 100 lives.
After collecting all 120 stars, a cannon will appear outside of the castle. Use this cannon to blast yourself to the top of the castle. At the top of the castle, you'll find Yoshi, who will give you 100 extra lives.
Wario's painting is NOT in Super Mario 64.If you want to see the proof, then check everywhere in the castle and see if I am right.
