There are retro revival consoles that aren't deliberately made to looks like the original incarnations. I think the issue here was that the consoles being sold were deliberate counterfeits of otherwise valuable original retro machines.
For instance, litigious as they are Nintendo has either been unable or unwilling to snuff out things like the RetroN machines which play original Nintendo and SNES cartridges (and Genesis, and some others) but don't claim to be a Nintendo machine or look like one in any way.
That said, I personally would totally buy a fake OG JDM Super Famicom just to have on the shelf, or even a shell just that looks like one.
Nintendo doesn't have a legal right to go after NES clones in the States because the patent on the NES expired and anyone is legally allowed to make perfect duplicates of NES hardware.
The only legal ground Nintendo has is software copyright for games they published and / or licensed ( probably just published )
Apparently the ones being pirated in this ring. My point is people still want retro gaming consoles and games. If the IP holders aren’t selling them, what do they expect people to do?
"Physical copies" is a big ask, considering they would also have to be selling the hardware to run those games.
To your credit, they aren't actually selling most of their back catalog anymore, since their e-shops that sold games for the WiiU/3DS are closed down, and with them, the Virtual Console died. Now we've only got a subscription-based library to play a much more limited selection of old games.
Either way, it's not Nintendo's fault you pirate games. You want to play old games, and you don't want to pay too much money for them, so you pirate them. Let's be real.
