@barbudreadmon My point was about GPL and about Retropie setup and Raspi OS. IMO it's good for people to actually understand what the GPL says and doesn't say, especially if they are involved with a project that is licensed under it. I agree that the non commercial licenses of Mame versions 2010 and less and many other included emulators would be violated by selling a retropie that includes those emulators.
This is of course assuming that the person doing it resides in a country that observes western copyright law.... US/European copyright law does not apply in China for example. There's probably a treaty that says it does, but it doesn't.
