Version 2.64 for the Murideo Six-G Gen1 and Version 3.02 for the Six-G Gen2 are both now on the web site for download. This firmware was verified bit perfect for all modes. Enjoy and if you find a problem let me know and i'll escalate it to their support, but it should be good now.
As far as the differences with the Gen2 hardware, I know they changed the power supply but with ver. 2.64 and Gen2 it works the same as the Gen1 unit I had. I believe there are some changes with the new 3.02 firmware and Gen2 and will report back.
