BlueCubeMod

ESP32 based GameCube Controller Bluetooth conversion for Nintendo Switch

v1: Mac/PC/PS4 supported (tested using Dolphin Emulator on Mac, for Switch/RaspberryPi, use an 8Bitdo USB adapter)

v2: Switch support only - no adapter required

Wiring:

• Connect pins 23 and 18 to GameCube controller's data pin (Red)

• Connect GND to controller's ground pin (Black)  

Build instructions(v2):

• Use this esp-idf fork here: https://github.com/NathanReeves/esp-idf

• Set up the esp-idf environment: https://docs.espressif.com/projects/esp-idf/en/latest/get-started/

• Get the BlueCubeModv2 firmware

• If you haven’t flashed an ESP32 project before, you need the port name of ESP32 for the config file. If using unix system, to get the port name of a USB device run:

ls /dev

• Find your device on the list and copy it. It should look something like: /dev/cu.usbserial-DO01EXOV or /dev/cu.SLAB_USBtoUART

• cd into project folder and run:

make menuconfig

• Paste your port name into Serial Flasher Config -> Default Serial Port

• Compile and flash the program, run:

make flash monitor
