YamiHoshi.nl challenges you to get Super Mario 64 DS, get 8 Stars, beat 2 Bowsers, unlock Mario, and that with a time limit of 15 minutes.
No problem at all, for the Tool Assisted Speedrun (TAS) community!

2 people, of which one of them being our friend, took the challenge to beat Super Mario 64 DS with 8 Stars, in just 14 minutes, and 23 seconds!
This game is filled with glitches, and these day’s DS Emulators allow TASsing.
By this, beating game perfectly is compared to a fart to the TASsers, while it’s a huge challenge for real time gamers, like us.
Before you get so shocked, SM64DS isn’t the first Mario game that got beaten with as less Stars as possible.

It’s successor, Super Mario 64, first got beaten with 50 Stars, as soon as BLJ’ing has been found in an Hispanic official Nintendo Magazine.
But later on, another BLJ spot has found, and allowed the player to beat the game in 30 Stars.
After that, a Bunny glitch has found, allowing the player to beat the game in 16 Stars.
Long after that, loads of BLJ spots have been found, allowing the player to beat the game in 1 Star.
Than the final BLJ method has improved, allowing the player to beat the game with no Stars at all!
We expect SM64DS to do the exact same thing later on.

What’s TAS?
TAS is mostly a shortcut name to “Tool Assisted Speedrun”, or “Tool Assisted Superplay” when no Speedruns are intended.
As the name applies, it’s a method that uses (modified) Emulators to run on your PC, and you’re using functions like slowdowns, save states, rerecording, frame-by-frame method, and more, until your run is as perfect as possible.

Derp, what’s BLJ?
BLJ means “Backwards Long Jump”, this allows you to perform the biggest shortcuts in history of gaming.
However, that technique is limited to Super Mario 64 only, and is totally removed in the DS version.
This made gamers look for alternative glitches, and these have been found.
