Its actually a carry case for a NES Classic and I designed and cut a new foam insert.

I am selling my Gameboy Zero, it includes case with custom cut foam for all the items, 4x Gameboy Carts that have been modified to house the SD Cards and have custom labels applied, a power cable that uses the original power port, a USB cable that uses the original multiplayer port, a 5V 2A AC Adapt...

@helder I'm Sorry if this has been posted somewhere else (I searched and couldn't find anything related). Where do I attach the USB cable on the 2.2 board? My issue is that all the buttons work except the D-Pad. I was going to try to reprogram it but I cant figure out how to hook it up to the PC sin...
