If you look closely you’ll notice there’s nowhere to put the game cartridge on this Super Nintendo system. That’s because this is a Rasberry Pi based SNES emulator that plays ROMs, not cartridges. Since the RPi board is used the only limit to what you can play is the board’s RAM and which ROMs you have on the SD card.
The case has basically been gutted and the unused cartridge slot was sealed with some Bondo before painting. In addition to the Rasberry Pi you’ll find a 7-port powered USB hub and a Teensy microcontroller board. The hub allows for the controllers to be connected via USB. The Teensy is recognized as a USB HID device and is used to connect the reset button to a functions on the emulator program. The power switch still works too. To make this happen [MIDItheKID] spliced a USB connector and a microB USB connector to the power switch. We think this draws power from the hub but we’re not 100% sure.
