A lot of those emulators, specially the SNES ones, make games better if not outright bearable. There’s a lot of games that I could not have completed without spending an absurd amount of time on them without saved states. The Nintendo games out there aren’t even exceptionally good, there are plenty of indie alternatives if people give them a chance. It’s biggest plus is that the brand does act in a way many AAA publishers fail to do, an assurance of a basic degree of quality.
