Nintendo Takes Down 144 Open-Source Repositories for Switch Modchip Firmware
The company's legal team has targeted GitHub repositories hosting firmware for hardware modifications to Nintendo Switch consoles, removing an entire network of projects in a single enforcement action.
Open-source code becomes target of Nintendo enforcement
Nintendo's legal department has turned its attention to open-source firmware projects that enable hardware modchips on the Nintendo Switch. A DMCA takedown notice from Nintendo of America, disclosed by GitHub this week, resulted in the removal of 144 repositories across the platform, encompassing both individual projects and their parent repository. The action targeted firmware supporting multiple modchip variants, including SX Core, SX Lite, Picofly, and HWFLY.
Hardware vulnerabilities and the modchip ecosystem
The original Nintendo Switch hardware contained an exploitable vulnerability in its recovery mode that could not be patched through software updates. Nintendo addressed this flaw in subsequent console revisions, including the Switch Lite and Switch OLED models. The modchip approach does not function on the Nintendo Switch 2. For owners of patched Switch units seeking to run unauthorized software, hardware modification remains the only viable path forward, requiring the installation and soldering of a microchip directly onto the console's motherboard.
These physical modifications depend on specialized firmware to execute voltage glitching techniques during the boot process, enabling the system to bypass security protections. The firmware code that performs this function has been the subject of Nintendo's enforcement action.
