I will probably use this guide. http://forums.modretro.com/viewtopic.php?f=33&t=8256
or this one. http://www.newsdownload.co.uk/pages/RPi ... stick.html
For the 3ds analog stick.
As for the screen well I will probably use this.

I am thinking that I will take off rca port on pi and solder directly, then use this guide
for power. Or I will wire to power circuit since I think this monitor turns off automatically when no inpuit is running.
