It has literally been over 10 years since I've played it. One of the bootup screens says "Xecutor2" at the bottom, so that tells me that much at least.
My main question is the three (3) dip switches on the front of the console. Someone else installed it for me, and I forget what each of them does.
I think that the left-most one controls whether or not the modchip is active; you wanted to toggle that one off if you ever went onto XBox Live, I think.
Can anyone help?
