*Edit* I guess I have more than one question..
While fiddleing around with the BIOS, I found that you can change the Disc drive speed and Texture mapping, what happens when I do this.
Also, when I change the aspect ratio to 16:9, it's still 4:3, and black bars come from up and down the screen. When I change my TV to "widescreen zoom" it acts like I'm stretching 4:3 to 16:9. Is that normal?
