I am trying to get this to work. I noticed on the site that it says not supported, but confirmed to work? I plug it into mine and get flashing blue and green light continuously. When I connect it to a Sega i/o, it works. I have tried to flash the firmware, but the software crashes before i can even flash it. ANy help?? I'm running Windows XP Pro 64bit for the MAME PC and my regular pc is Windows 7 64bit. I have tried both, and get crashes immediately.
