Nintendo recently released the Switch 2 firmware update 21.0.0, which, besides minor changes, has rendered some third-party docking solutions incompatible with the console. Since the console’s launch, various companies have reverse-engineered the console’s protocol, power draw, and chip requirements to mimic Nintendo’s official dock, which is bundled with the console. These companies must now determine how to re-establish compatibility.
The immediate consequence of the update has fueled speculation that Nintendo intentionally disabled these third-party accessories. However, Nintendo released a statement via Kotaku, asserting that it “does not have any intention to hinder or invalidate legal third-party dock compatibility.” This ambiguous response suggests that while the issue may not be an intended consequence of the update, Nintendo has seemingly created a distinction between “legal” and potentially “illegal” methods of creating third-party docks.
The situation is further complicated by the fact that not all third-party docks were affected. Accessories like the Viture Pro mobile dock and Antank’s S3 Max reportedly continue to function, with the latter’s representative attributing its continued compatibility to a “proprietary casting chip solution” that offers higher fidelity with Nintendo’s private protocol compared to other market solutions.
This incident raises critical questions about Nintendo’s future strategy. It is unclear if more third-party accessories will be affected by future updates or if the company is implementing a constantly reconfiguring proprietary handshake to keep external accessory makers in a perpetual state of catch-up. This raises the possibility of Nintendo developing a formal licensing program, similar to Apple’s MFi certification, that would require manufacturers to pay a fee to guarantee out-of-the-box compatibility.
Ultimately, Nintendo’s goal remains to steer consumers toward its more expensive official dock and discourage third-party manufacturers from offering similar gadgets at a lower cost. This creates a challenging environment for companies like Genki and JSAUX, who are planning to launch compact docks this year with Switch 2 support, forcing them to ensure their compatibility remains a viable selling point.
