hi there from germany,

did everything as mentioned on retrode.org but got this fail message "verify device fail at 0x00000.
Now my retrode wont let me copy games (f.ex. gameboy via plugin) to pc.

please help, what went wrong?

thx a lot!

Hard to diagnose remotely.

You might want to try the update again.  I had this happen once and I restarted and got it updating again.  If your attempts to update continue to fail, then look into one of the alternative updating options.

People with problems updating on Windows systems are having success using Linux.

Thx for the answer!

I tried it many times and on two win systems (win7 64 and win10 64) and always got the same result.

Where do I find the alternate update options?

If you can't get it working on Windows, then there are options to update using Mac or Linux.  The instructions are on the Retrode firmware page.

I'm very sorry but I tried now the whole day to get some linux work but this is so complicated I have neber used this and I dont know how to install a dfu programmer.... gave it up...

Is there no way to get my retrode work on windows?

You might try reinstalling the driver.

Pay close attention to newbie2's posts if you're having difficulty.

I'm very sorry, but I tried everything mentioned in the Links but nothing works....

After the workaround thing it enters dfu mode correctly, but the flashing fails at ,,verify device fail at 0x0000"
I tried several firmware hex for Retrode2

Also as soon as i only press the reset button a device called ,,Retrode Retrode 2 USB Device" appears at device manager with some microsoft drivers... deleting, deactivating, nothing helps....

Looking back through old support posts and FW 0.18c was mentioned several times.

Matthias had a couple recommendations:
Windows users: Sometimes Windows gets the USB drivers wrong and you need to trigger re-detection. To do so, please start the registry editor as an administrator, search for keys that contain the string "Vid_0403&Pid_97c" (Retrode identifier) and delete them all. This will basically clear Windows' entire memory of that USB device, and next time you connect the Retrode, it will re-initialize all the drivers.

Apparently, the firmware upgrade (DFU) bootloader tends not to work on USB 3 ports. I'd suggest you try updating the firmware on an USB 2.0 port or through a hub.

One user that was having problems updating finally had success using an old laptop running XP.

Ok I will try that.

Besides, another problem finally is solved. As in my first post mentioned, I couldnt copy any gameboy games via the plugin to my pc. After days of try and error I read the config file and there where no values at all rom entries!!!
How could this be???

Easily wrote them in and the Retrode works fine again!!!!

But the flashing thing I have to try as you told me above, hope this will help!
