RetroN 5 is officially a thing, apparently

Although, if they add that, it would kill all those flash carts market for the most part; because you can buy a multi emulator console for less than 100 vs a cart for 1 console only for over 100.

I disagree

The people buying Everdrives, Cuttle Carts, PowerPaks, and so on are the diehard classic gamers. Much of this segment will stick to original hardware since that's what they love, they already have the consoles, they're more durable than any cheap 21st century Asian clone will be, you're guaranteed of 100% accuracy, compatibility is guaranteed, and it's nostalgia. There will still be demand for multicarts for such hardware and multicarts will likely be much more versatile than any cheap clone that can load roms off flash memory ever will be.

As for the rest of what you posted, I'm very skeptical. If the US government had actually put the cabash to protecting copyrights for obsolete videogame software, that would be big news in the classic gaming world. I suspect the old adage about not being able to put the genie back in the bottle is why rom sites don't seem to be gone after with the vigor of earlier years.
