Super Mario 64 DS is a game made only for the Nintendo DS by Nintendo's Entertainment Analysis and Development division, and published by the company itself on November 21, 2004, in North America, December 2, that same year, in Japan, on February 24, 2005, in Australia, and on March 11, 2005, in Europe, as a remastered edition of its classic Nintendo 64 title Super Mario 64.
Because the original game had such a large cult appeal, the development studio didn't add serious changes to the new version, keeping the gameplay and the story largely the same, but did make a few improvements, in terms of graphics, thanks to the more powerful hardware of the Nintendo DS, and even added new characters like Yoshi or Wario, who have special powers different from Mario, the protagonist.
HINTS
Secret areas
After entering the castle, go upstairs. Go halfway around the pillar in the middle and enter the door to the right on your map. Go up the stairs in that room and get a Power Flower. Go into the mirror and into the room in the middle. A Star will be hovering above the ground in its room of invisible walls.
Drain water under bridge and Star
After getting Wario, go to the basement type place. Go through one of the doors with no star on it. You will reach a sign that says something about the two pillars in front of you. Ground Pound both of them, and the water will sink. After that, go outside close to under the bridge. There will be one of those black brink type things -- make sure you have Wario. Then, ground pound it. You must collect all the red coins to get the Star in that secret spot.
Easy Stars
Some very easy Stars appear when you talk to some Toads in different rooms around the castle.
1-Up Mushrooms
-When you get a power-up mushroom(that makes your character bigger), start plowing down enemies, signs, etc. A number will appear after every object you hit. After the number "8" appears, you will earn a 1-Up for each enemy hit.
-When you enter the castle, go to your right. There will be a door with a "3" on it. Enter it. There will be a painting with bubbles inside. Go to your left. There will be a raised box up in the wall. Jump inside and there should be a 1 Up Mushroom.
