that's why I'm asking... I'm interested about that onI have seen one for sale in Facebook, if anyone here that have it , i think he can make an update un working or unlocked version of it to some existing owners of namco es3 systems
I missed this, that is actually the error code i'm getting on mine (https://www.arcade-projects.com/threads/es3-tekken-7-fr-round-2-security-dongle-error.20657/) I guess that solves that mysteryThe USB update will run, but when it will be updated your old security dongle (JP1 or JP2 won't work anymore, Dongle ERROR 3 from preAmAuth).
A good way to "brick" your ES3.
