      Hello.
      I have measured 5V on the VCC pin.

      I have tried libusb and so, without any result with avrdudess.

      So, I used Microchip studio to try to made the update and it seems to work ! 😀
      After that, koryuu seems to work fine. How can I be sure that I have the good version of the firmware ? I only see that when I press the “input” button on the koryuu , the OSSC switch the resolution (and after hitting the 2 buttons simultaneously , the Koryuu’s LED flash a few times in less than half a second). So it’s Ok according to the last version of firmware I presume?

      Thanks a lot ! best regards.

        Ok thanks for all these information ! I have used the WinUSB drivers with Zadig.
        I have uploaded the drivers on my PC with microship studio with success.

        I will tried tomorrow the other options, thanks a lot !

        ps: in avrdudess, I only see STK200, not the 500.

          Hello, Ok thanks but I don’t have exactly the same model of programmer.
          I have this one:

          I have opened it and I only have two choices : 3V or 5V (no Target OFF jumper)
          I have try both but AVRDUDESS didn’t see in any case the controller.
          When I tried with Microschip studio software, the soft see the controller of the Koryuu. So, it seems to be OK but I’m not sure that the software is totally compatible with this kind of firmware and I’m afraid to delete the internal firmware without to possibility to update it finally.
          Best regards

            Hello!
            I have try to update the Koryuu with an Atmel Avr ISP MKII but I failed 🙁 (AVRDUDESS didn’t see the controller inside the Koryuu )
            Perhaps a voltage problem with the jumpers at the down left part of the programmer?
            May I used Microschip studio software (Programming tool module) instead ? It’s seams to see the correct controller inside the Koryuu but I’m afraid to lost the internal firmware in case of failure so I prefer to ask you before I try. Can I try directly without any modification of the PCB/connectors or should I made something before ?
            Thanks a lot.
            Regards

                  Hello!
                  That was I thought. Thanks a lot for the information.
                  Well, selectable audio can be a good thing if possible (and/or for the pro version 😉
                  I think I can’t wait the pro and buy the Keico now ? … and the scart cables … if retrogamingcables.co.uk answer me about the availability of the Neo Aes sacart+jack stereo cable …
                  Have a nice day
