Thanks for the help - really great.
So firstly I am trying to update SSB.
However I have no luck with this WUPinstaller or rather NUSGrabber. NUS Grabber seems to do nothing - well when I run it, a window really quickly opens then closes. I found a program NUSGrabberui and it has a list of stuff - games etc but when I choose SSB and try to download the latest or any update I get 'there was an unknown problem when downloading'...
I am using it on Windows10 and generally am competent with pc's etc..
--------------------- MERGED ---------------------------
I am trying to download the SSB update using JNUSTool but I have no idea if thats ok or not. Really don't understand NUSGrabber! Well don't understand JNUStool but at least it does something!
Still trying. Do I need to decrypt the ssb update or just download it?
After more research I am not sure NUSGrabber or NewNUSGrabber or NUSGrabberGUI work anymore? Trying to download with JNUStool..
Settled on using Uwizard. Downloading update now. Seems to be working!
Additional follow up: I have worked out how to use NUSgrabber, it works in a CMD prompt window and needs the title id after it:
"NUSgrabber.exe 0005000010145000" for the latest update for SSB EU.
I was able to find a working title id from here:

The version of NUSgrabber I am using comes from the WUPinstaller homepage:
http://wupinstaller.com
NB there are apparently a few versions of this around but this one does seem to work and the WUPinstaller homepage states that this version 'This is a special version that directly renames the files to work with the installer.'
You can actually see it downloading the files from Nintendo so that is quite fun.
I will report back when my super slow rural broadband finally coughs up the update! mmm not sure that title id is correct - so far the download is 9GB and still going...
Final update. All working! It was pretty simple in the end, just needed the correct version of NUSgrabber and the correct title id. The latest update for SSB is around 3gb not 13gb. The version of NUSgrabber from the WUPinstaller page does download slightly different files than uwizard so don't use uwizard/JNUStool for this purpose.
Thanks again and hope this helps someone else!
