I am interested in creating and selling hardware for emulating old arcade games. However, I am very aware that there could be several legal issues here.
First of all, many emulators are open-source, but have non-commercial licenses. Would it be legal to create a piece of hardware that would download and install the software upon the user's consent?
If the above is legal, is it necessary to ask for user confirmation?
Theoretical Software: RetroPie, which includes many non-commercially licensed components. All components are open-source.
