Sonic Generations (2011) remains a popular title in the PC modding community, yet it suffers from a persistent runtime error: "The detected configuration does not match your current hardware."

We document common failure patterns, assess user-led workarounds (deleting configuration files, GPU spoofing, and version overrides), and discuss implications for digital preservation of early-2010s DirectX 9/11 hybrid games.
