You are completely missing the point here. First i am talking about these new emulators-in-a-plastic-box things, which are definitely not the classic models.Just because 'you' dont see the need. What about people who collect and maintain 'Classic; cars. These are the orginal cars warts and all not modern replicas. They might use them or just keep them in the garage . You seem to like to 'control' other people knowledge acquisition and experience and the guise of beige helpful. I have rediscovered my interest in these classic computer precisely because someone isnt telling me what to do.
I perfectly understand people who collect classic computers, a friend of mine does, also i'm a fan of Retromacave. But what we're talking about here is not that. It's an emulator running on a cheap chinese knock-off SoC, put in a modern box, with absolutely no relation with the classic build apart from the looks maybe. You are talking about collecting classic cars, then it's like trying to dress up today's Ford Fiesta (or a small Kia, since we're mentioning chinese knockoffs) into an early 1970's Firebird TransAm, and sell it at the price of that classic car or even more: I still cant see the point. Like i said, if you want an emulated thing, the RPi will do it better than those cheap SoCs as it wont be limited. If you want the classic thing for collection, then it's not the topic we are discussing here.
