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.
I posted this in another part of the forum but maybe it will get an answer here. Why can't you use a PSONE Screen on an Atari. I haven't tried yet but Ben said it doesn't work. I would like to know if you can hook it up a special way.
