I agree It’s too bad VSigFile seems to be abandonware. There have to be quite a few DSP4000s, DSP4500s, DS7000s, DSP7500s, DSP7600s, Orvilles and H8000FWs out there! (Did I miss any supported by VSig2?!)
In addition to the info provided by atarirob above, I also found Adam-I-Echo’s videos helpful. Here’s an example: https://youtu.be/y71fpL6c-dg.
