Veteran N64 developer and hacker Kaze Emanuar has publicly challenged Analogue 3D's claims of cycle accuracy and "100% compatibility," presenting side-by-side tests that show slower performance, missing hardware behaviors, and failed system checks compared to an original Nintendo 64. While he still considers the FPGA-based system a strong, affordable option for most players and notes that firmware updates may address many issues, Analogue has yet to respond to the mounting concerns from speedrunners, modders, and preservationists.
