In what way is it fake? I'm not sure if you understand the purpose of it if so, or are there errors on loading? Feedback appreciated.

Pretty usefull as an EMT. I used it all the time when i had a 935. Hoping that support for the new Fenlx 6 line will come soon, because there is no good alternative out there.
