Your first link doesn't work.
I've never done this stuff before, are there clearer instructions?
I fixed it.

Nah. No clearer instructions from me unfortunately.
I was considering making a video on how to do it, but I just haven't had the time.
I'm not an overly technical guy, but I'm good at following instructions.
If you go back a week on this you will see I was asking the same questions you were.
I found some vague instructions as people posted these instructions for hacking the original NES mini from a Mac and filled it in myself when i ran into trouble.
Here's some tips from me.
You need to download virtualbox. Its basically a free version of parallels.
Theres an extension pack that you would also need thats on the virtual box site that i linked called VirtualBox 5.1.28 Oracle VM VirtualBox Extension Pack
Then download a 90 day demo of windows 7 from the second link.
You need to enable the USB Controller and select usb 2.0 from virtualbox (which is why you need the extension pack. Otherwise you can have issues installing the drivers.)
Theres a way to select the usb device filters.
Once all that is set, the hacking can commence. The only issues i ran into were usb related, but setting the usb controllers can fix that.
