What are some of you favourite remixes of retro video game soundtracks?

Here's a few of mine:

Megaman 3 theme http://www.youtube.com/watch?v=mcExlu3NQaY

Does the Metal Gear cell ringtone count?
Used to be common everywhere, hey I still like it!

There were a couple remixes on PSX Dance Revolution discs, I think Gradius was one of them.
