Also a couple of other things - I just took a look at ETA prime’s video on an arcade1up conversion; I don’t see him using a third party image, he is just using the official image it seems with the “showcase” theme which you can download from the Retropie official version. There are a lot of cool themes people have created for the official version. The other thing is that just because ETA prime does something doesn’t mean people here necessarily support it. The guy seems like a good guy and I have certainly watched his videos for help but ultimately he is a profit-making enterprise for YouTube views, ads, affiliate links, etc, and (I think at least) he is not an official part of the RetroPie Project in any way. Finally keep in mind as you go forward on working on your project that videos of any kind are necessarily snapshots in time - they can be helpful but they can also become quickly outdated as soon as retropie is updated.
