"Screens that you CAN'T use:
1. Game boy, game gear, DS, or PSP screens.
2. iPod or MP3 screens.
3. Most portable DVD players.
4. Cellphones.
5. Pretty much anything that doesn't take a normal signal.
Screens that can sorta be used:
1. Portable DVD players, certain types. You have to keep the main board.
2. GBA. You need an input cart and the whole friggin' gameboy.
3. Nomad screen. Accepts RGB, but expensive and crap.
4. Laptop LCD. If you have a certain type and about $200 to blow on an encoder, that is.
