Would creating an image require me to have an SD Card reader?
I believe that has been the source of the majority of my current hurdles, however I liked the flexibility of having NOOBS just while im getting to grips with the RPI3 and what im planning to use it for.
Cheers for the advice though.
UPDATE:
By disconnecting my Pi from the internet, I was able to install the Jessie Version 8 of Raspbian, otherwise it was going online to retrieve Stretch Version 9
From here on out - it's a standard install, Binary options were available, and now its all setup.
Seen as I already have Pixel Desktop Installed how do I enable the Pixel Desktop Option in PORTS without "Installing Pixel Desktop" via the RetroPie-Setup?It didn't seem to work last time.
