decided to go the linux route, however its been quite a while since ive messed with it, do I need to download the above listed minimal install then copy the text listed above save it as retropie_install.sh place it where noted then run the script, or run the items one at a time?
Thanks for the help all
Yep, you need to install the minimal Ubuntu version, I recommend v18.04 but v20.04 is (obviously) the latest. After downloaded and installed (from USB preferably) to a storage device, you need to create and either copy the "retropie_install.sh" file to samba share (this has to be installed and setup, check /etc/samba/smb.conf afterwards) or copy it to and from a USB drive and run that file. Don't forget to do "chmod +x retropie_install.sh" after that it's just a matter of executing retropie_install.sh
If you don't want to bother with that, just download MizterB's bootstrap.sh file, it's way more automated aka user friendly and has some advantages over my script (like no terminal output when launching a game)
Included an attachment of how the setup looks when done.
