Ars Technica - How the demonization of emulation devalues gaming’s heritage.
"To highlight the extent of the problem, Cifaldi contrasted Duck Tales—a 1989 NES games that still attracts considerable attention on YouTube and Twitch—with Uncle Buck—a mid-level cinematic John Candy vehicle from the same year. Duck Tales can only currently be purchased as an original NES cartridge or in a heavily altered "Remastered" edition for modern consoles. Uncle Buck, on the other hand, is available in multiple DVD and Blu-Ray packages, and on hosts of digital download services for rental or purchase. In fact, all of the top-grossing films of 1989 are available in modern formats, but the same can't be said for any of Wikipedia's most notable games from the same year (save for Mega Man 2, thanks in part to Cifaldi's efforts).

'These movies have always been in print,' Cifaldi said. 'Games could have been the same way, except we demonized emulation, and devalued our heritage. We've relegated a majority of our past to piracy.'"
