Nothing special that I note, it just appears to be a bunch of typically separate items (SDR#, DSD, DSD+, plugins, etc) all thrown together in one archive, along with the so called "SDR Ultra" which is a custom compile/build of SDR# as far as I can tell. It's got some issues: whoever compiled it used an older Borland compiler because it complains about a missing component when it's first fired up (borlndmm.dll) and also complains about another missing component (ExtIO library ExtIO_pappradio2.dll) but it still does load.
Can't see anything special about it, my first impression (which is my opinion, of course) is "Ugh..." and that's all I'm going to say.
Also sent the archive to VirusTotal just to check on it, seems clean with 4
possible false positives that were originally detected but after a re-analysis it showed 3 because several of the antivirus scanners were timing out/not responding. Here's the link for the results if you're paranoid to some degree anyway:

Got no use for this custom compiled thing but maybe someone might like it. I prefer good old plain vanilla SDR# personally.
Apparently the name is "SDRsharper" so whatever.
