Hello! I hope anybody can help me: I bought at EBAY an MZ-N10 MiniDisc-Player, the seller wrote in his description that there ist the possibility to upgrade the firmware, because he bought the Player in China and so the firmware/menu language is not in english or german. Is there a possibility to upgrade the firmware or to change the language from a chinese player? Thank for your help! Greetings, Thorsten
