The OP didn't clarify. But if there's a claim of 100% faithful recreation, I'd expect something to back it up, like time- and frequency-domain comparisons of input and output with different test signals. Or at least something. But there isn't anything.

The video claims: "It utilizes the actual DSP characteristics of the original to bring that specific sound back to life." The author admits they have never programmed DSP. So how are they verifying this claim?
