I used the buttons of my old SNES controller and added a 4 button board I got from eBay.

Update 1
I got most of the parts in (still waiting on the USB hub and the Mini USB for charging). I'm going to solder the Powerboost, Battery, screen and audio tonight.
The 640x480 VGA screen is glued in place. Last night I ordered the screenprotector from http://www.retrofresh.uk/ (Thanks [mention=@dominator]Dominator[/mention]) because you can see a little part of the screen and the gray border will finish the build.
I used the Start & Select buttons from the SNES controller to use as the L & R Buttons. I glued two tacticle buttons on the inside. The holes aren't the cleanest

I will post some photos when I have a working screen
