So, i grabbed an old portable DVD player at my local resale shop (I was allowed to verify that it worked, but the adapter was unfortunately for another device). It's one of those headrest mounted ones that's supposed to be a two-piecer, but they just have the one part. I know the model is RCA, but as far as anything else goes i'm gonna have to post pics of it. Basically, I want to put a Raspberry Pi and run either retropie or recalbox so my lady can retro game on the go. can anyone point me to similar projects on or off the site (or impart wisdom where ya can). As always, any help is appreciated. Y'all have a great day, and thanks in advance for any assistance given.

Some pictures would help in figuring out what you need and depends how much you plan to tinker with it, are you looking for a quick hookup or plan to solder things in?
