Thank you for viewing. I have tested the item on a Super Famicom console before listing it. This is a genuine Nintendo S-terminal cable. The cable has a coupler, so it is likely the first-generation S-terminal cable. Please refrain from purchasing if you are overly concerned about details. This is based on my personal assessment, so please understand. Due to measures to prevent product substitution, I cannot accommodate any requests based on your circumstances. Please only purchase if you understand and agree to these terms.
