OpenGCC

This is a GameCube Controller firmware designed to be extensible to easily support any RP2040-based controller hardware.

Supported Controllers

• NobGCC
• PhobGCC 2

Features

• Analog stick calibration
• Button remapping
• Trigger modes
• Dual settings profiles
• Notch calibration (Planned)
• Snapback filtering (Planned)

Building the Firmware

1. Follow the "Install the Toolchain" instructions for your platform in Getting started with Raspberry Pi Pico (MacOS and Windows instructions are under "Building on other platforms")
2. Download the repository
3. cd <repository directory>
4. git submodule update --init --recursive to retrieve the Pico SDK.
5. mkdir build to create the build directory
6. cd build
7. cmake .. to write build files. Use cmake .. -DCMAKE_BUILD_TYPE=Debug if adding features to create a debug build instead, and cmake .. -DCMAKE_BUILD_TYPE=Release to revert to a release build.
8. make to build all firmware targets. Compiled firmware will appear in build/controllers under each controller's subdirectory. To build a specific firmware, run make <controller_name> instead.
9. Plug in your controller in Mass Storage (Flash) Mode and drag the UF2 file onto the device.
