Counterfeit and knockoff arcade machines are a growing concern for collectors, operators, and enthusiasts. The most common issues include unauthorized reproductions of classic arcade cabinets, often with inferior components or incorrect artwork. Some counterfeit machines mimic rare or high-value titles, deceiving buyers with fake labels and counterfeit PCBs. Another issue is the use of emulation software in knockoff cabinets, which violates copyright laws. Additionally, some sellers falsely advertise refurbished or "restored" machines that are actually cheap replicas. These scams not only harm the arcade community but also devalue genuine collectibles. Always verify authenticity through serial numbers, original parts, and trusted sellers to avoid falling victim to counterfeit arcade machines.
