Classic 8 bit NES. Save state and upscaling are all great features everyone appreciates, but what I really hated was Nintendo’s hard, square controller! Using a modern, soft rounded controller to replay my classic NES favs is just so much better. And yeah, save game state is a literal game changer, lol.
Oh, Brother.
No seriously, buy Brother printers instead and avoid (at least some of) this enshitification.
