wii u developer console won't boot retail disc. pics. help?

I bought a used wii u from an online ad in San Francisco just a few days ago. Met up in a public place with an outlet so I knew it worked before I paid.

I was told I'd need to connect to the internet and update it before it would play games.

I might have screwed up before I got that far, but it's a rare piece of gear and I'm not really worried. Minorly frustrated maybe.

Pictures are included below. It has a green face plate like the wii dev unit did. The controller has a boxy bit sticking out of the middle top edge.

I tried booting NSMBWu and it won't recognize the disc.

I clicked something called DEVMENU but it wouldn't let me get back out of it.

That was when I had a 1080p HDTV to test it on.

Now I'm at home with only a 720p and it doesn't seem to give a signal to that tv.

Looking for help online. Internet hasn't been much help.

I've hammered search engines and searched this forum and lots of others looking for help, reference, images, anything. There doesn't seem to be any available public information about this. At least not yet anyway.

I spoke with a guy who said he'd helped test a sega title for wiiu, he said the menu looks very old. TVii? He may be right.

I'll keep messing with it whenever I can get my hands on a 1080p monitor, tv, screen, whatever. But my current tv isn't showing me the DEVMENU screen in the pic below, so I'm stuck for tonight.
