Super TapTo Boy
Super TapTo Boy is a custom case project created by Phoenix whereby a SNES shell is used (with a SBC inside) and is used in conjuction with a Super Gameboy (for reading the games). The Super Gameboy houses a PN532 NFC reader inside that is connected to a SBC (DE-10 Nano or Raspberry Pi) which itself is housed inside the SNES shell. They are then connected on the inside to each other through a wired USB connection.
The games' path is written on a NFC chip or tag via the TapTo Life app and the chip is then adhered to the inside of a GameBoy cartridge that is subsequently read by the NFC reader (which sits inside the Super GameBoy). This will in turn start the game on the desired hardware. You can find more information on how to use the TapTo Life app to write games to NFC chips here.
Introduction
This project started it's life after contemplating on how best to use physical media together with sofware or hardware emulation. Since the MiSTer Project and the multitude of Linux-based Emulation operating systems have no physical media for games, a lot of people resort to modding and using their own classic consoles for the most nostalgic looking and feeling experience. Currently software and hardware emulation have come a long way and are in some cases (almost) interchangable with original hardware accuracy-wise. The abscence of physical media keeps people from viewing this route as a 'complete' and authentic experience.
The TapTo project introduces a new way for people to fill this gap with physical NFC cards. Super TapTo Boy tries to improve upon this concept with physical cartridges to replicate the feeling of inserting games and having a classic console to look at while keeping the cost relatively low compared to modding original hardware for the same performance.
The build
Here I will talk about building process of the Super TapTo Boy. As a disclaimer, the process will require some soldering skill and cutting/removing some parts of your existing hardware. I would rank this process as intermediate. If you like to tinker, read on, otherwise try to reach out to others for help before you do some irreversible damage.
With that out of the way, below I will list the requirements for this build. Try to acquire as much as you can before you begin.
First of all, we need either a European Super Nintendo or Japanese Super Famicom. The American Super Nintendo could probably work too, but since it's shape and size is a little bit different and I do not own one, I cannot with 100% certainty say that all of the steps will work 100% so your mileage may vary.
Secondly, you will need a Super Gameboy and some Gameboy cartridges. These may be bought online or they could even be your own cartridges that you want to put a NFC chip into (more on that later).
Preferable you will also need a 3D-printer to print some things for the build, but they are cosmetic and not mandatory.
You will also need some cables and other items like (also keep in mind that we have limited space in the case, so the smaller or shorter the items are, the better) :
- A male to female HDMI cable (I used a 20 cm one).
- A small USB hub for inside the case to hook your devices to.
- A Bluetooth dongle
- A WiFi dongle
- Female USB-A and C ports
- A 90 degrees USB-C to USB-A cable
- Some shrink cables
- DuPont cables
- Soldering iron and wire
- A Pico Pi (for the front controller ports)
- Round NFC tags (NTAG 215)
- A PN532 NFC reader with USB-C (black one)
- General tools like a plier and screwdriver
Reading the Super Gameboy.
Open up the super gameboy and remove everything including the PCB board. Then you will need to cut some up the support bars to make room for the NFC-reader.
