For users on the latest Ryujinx builds, having a verified, up-to-date key file is the difference between a seamless 60FPS experience and a black screen on startup.
To understand why Ryujinx needs "prod keys," one must understand the security architecture of the Nintendo Switch. Unlike older cartridges that could be simply dumped and played, the Switch utilizes a robust encryption system. Game files (XCI and NSP) and the console's firmware itself are encrypted to prevent unauthorized execution.
