SVN r6389: N64 driver

And now, an unusual type of WIP. Let's call it:

N64 Driver: What It Can't Do

It can't display Bio F.R.E.A.K.S.'s text properly.

It can't display the background images in Mario Kart 64 properly.

It messes up on some of the UI art in Automobili Lamborghini.

It has a strangely offset screen in The New Tetris and the Rampage games.

It hangs on the first frame in Banjo-Kazooie.

It also can't boot a number of games; those including Chameleon Twist, Perfect Dark, GoldenEye 007, Banjo-Tooie, Conker's Bad Fur Day, Resident Evil 2, Indiana Jones and the Infernal Machine, Star Wars Episode 1 - Battle for Naboo, Yoshi's Story, and many others.

At this point, I think it might be best for anyone interested in contributing to the N64 driver to look into the main CPU or machine/n64.c-related issues keeping these games from booting. smile
