This thing is ultimately just a MiSTer Pi with a SNAC adaptor, as far as I can tell. All the usual caveats about cost/benefit when buying into FPGA hardware emulation apply. It's probably more interesting of a purchase if you have a CRT you want to use with emulation than if you care about using a 4K flat TV.

But hey, it looks nice and it's way cheaper than the DE-10 Nano-based OG MiSTer setups, so... I'm not saying it sucks, just that it should be put in perspective.

I'm not super clear if it will run all cores out of the box, though. I assume so? The announcement is a bit light on detail beyond PSOne support.

EDIT: Never mind, it's buried in the middle of the promo page, but it's there:

SuperStationᵒⁿᵉ is designed to play PS1 games, but the hardware fully supports the MiSTer FPGA platform
