In March, some one in a Facebook Group I'm in shared a video of the Raspberry Pi in an NES Cartridge mod, and a bunch of people said they wanted one. I wasn't keen on the cartridge housing, so I decided to make my own twist [and I know I'm not the first to do it, I just did it a little different from what I've seen on the net]. I started with an SNES, gutted it, dremelled out all the plastic standoffs- or most of them- to make room for cabling and the devices. Then I soldered a Mayflash SNES to USB adapter to the back of the SNES's ports, placed a Raspberry Pi 3 in, hooked that Mayflash up, custom fit a micro USB and HDMI panel mount extension to the rear port panel, put in the famous PowerBlock attachment for the Pi, and hooked up the system's power switch to the PowerBlock. The end result- a very nostalgically intact Pi SNES. I call it the SNES+. To cap it all off, I put in a wireless keyboard/trackpad combo USB adapter within it, picked up an 8bitdo SNES and NES30 pro controller, installed Kodi- and now I have one sexy ass set-top/emulation box. That Facebook group went nuts, and since then, I've churned out 12 of these for members of the group. Currently on a break. Very tedious and exhausting to do and have it look great. But, none the less. Functional power button, functional controller ports for real controllers, functional lights, and proper power/AV port placement gave me a pretty solid result. The buyers are lovin' 'em. This was made when I was still selling, so disregard the mentions of buyable options, lol. Page with build process: http://imgur.com/gallery/BJRMV
Looks like a fun project. Out of curiosity, was there a reason you didn't use gpio for the snes controller ports? The gpio header also has 5v in case you need to free up that usb port for something in the future.
