I received my upgraded Flashback today and I am more than impressed by the professional product and superior service. Total time from mailing my old, non-functional flashback to return was a little over one week. This may be due to all the USPS trucks serendipitously lined up, but I'll take it. The front end is very intuitive and the upgraded emulation totally enhances the experience. My hats off to Byte Knight for a job well done!
