The box has enough room for the Xbox 360 Controller, Xbox charge cable, wireless receiver, micro usb cable, and power supply.
I painted the box yellow and let it dry. Then I used a projector to trace the question block logo off of Super Mario Brothers onto a folder and cut it out. I did the dark grey first and let it dry overnight. Once it was dry I did the orange.
Currently it has NES, SNES, and SEGA emulators. It uses an xbox wireless receiver and a 360 controller to play the games.
