I recommend doing a NES or SNES If its your first portable. If you would like to stick with the gamecube, it is going to be tricky. Read the megastickies for screens to get ideas on which to use, and read the gamecube (or whatever console) megasticky Several times. When you get a good idea on how everything works, make a worklog and post pictures and updates and members will help you on the way. I recommend using a 3.5 " ebay screen btw for this particular portable, 5" is pretty big for a gcp (imo)
