If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

Are you sure a 7" screen will be enough for your xbox laptop? It should be fine for single player, but if you want to play multiplayer it could get cramped. You could fit up to a 13 or 14" screen (depending on how much you downsize the xbox).
