I have a Namco System 369 arcade board that runs Tekken Tag Tournament 2 Unlimited. Unfortunately a week or two ago, I got a usb error. It took me a day or so to realize the second dongle (2gb usb drive) died that carries all the data downloaded from the Namco servers while they were still online. Luckily I Replaced the drive with a Spare 2gb flash drive, after a long formatting process, The game booted and works just fine. However now it has no custom characters or costumes it pulled from Namco's servers back when they were still online. Does anyone have a working TTT2u with proper data dongle in USB2 that ha the Namco server data they would be willing to provide me an image of so I can have the custom data from Namco once more? All you would need to do is put the data drive in a computer and use a free program like imageUSB to pull the contents off.
Sending a PM too but you think you might be able to help with a T6 vanilla dongle image. I finally got a 357 to put mine in and it gives me an error.
