How many volts does the xbox take? Does it need two voltages like an N64? Oh and how much to the controller?

-12V means just that....negative 12 volts :P!!!......you can get dc-dc converter (try a mini-itx one) that output negative voltages :)

You can also use 79XX negative voltage regulators to get the negative voltages.

Sorry, just did some research, and found that you will have to get -12V some other way, but you can still use a 7905 to get -5V, because it can take an input of -12V.

No, use a +DC/-DC adaptor to get -12V, and then either use another +DC/-DC adaptor, or a 7905 to get -5V.

if you're gonna split the controller, i big one would be good. if you're gonna do that one thing that doesn't involve the controller case, use a small one

If you can solder well use a S because its smaller but if your crappy (like me)
then use the big one, it should be much easyer to work with.
