considering you can still just search on google for "super nintendo full rom set" and find a working link within two minutes, all these only clickbait.
if you want to actually talk about preservation, talk about copyright abolishment, everything else is basically irrelevant.
also stop shilling these fpga trashboxes, you've got a million devices that can emulate games just as good that aren't single-use electronic trash.
They're mostly just making finding roms more inconvenient, I remember when every other rom site had literally every game for all the old consoles available for download, nowadays I get a lot of "your government blocked this website" or the site doesn't have all the consoles
