Basically as title says?

Obviously I know that a screen is needed. But what else???

Ciggy lighter adaptor or some wiring through the car to the battery attached to an inverter, and thats it. Find somewhere good to put it, and spend £30 or so on a power inverter and that's it.

cool, thought that whats all that is needed. How power does the inverter hav to be though? 150W? 300W?

and would just one of those screens that people normally put in cars do?

yep, just a normal screen will do, but you will need a head unit with an AUX input if you want the gamecubes audio played through it

i'd say a 300W power inverter will be powerful enough

Well, when its in your car, wind down the window and throw it! as hard as you can!

I had gamecube mounted and working in my previous car. :) My onverter had 150w, that's enough. The gamecube uses VERY little power! You can mount it in the boot, the connect the inverter through a button which you can have in the midconsole. I had it like this with wireless wavebirds, and it worked perfectly. :) The gamecube and the inverter can be "on" at all times, and you just shut the power using the switch in the midconsole. :) Hope you understood what I meant :p
