TI-83 emulator?

[BustedNuts1]

I tried searching for TI-83 and there weren't any matches, and it won't let you search for TI 83 because TI is under the 3 letter minimum, so I apologize if I missed it.

Anyways, I say a youtube video of a mogul with a TI 83 emulator on it. Anybody know where I can get this? Anybody tried it? How well does it work?

thank in advance
