They all must go. You wouldn't even believe the loss of revenue Nintendo suffers from the mere existence of SNES emulators. Money is being stolen right out of their pockets. Experts say they might never financially recover. ^[citation needed]
I'm in no way condoning Nintendo's behaviour, but the idea that they don't make any money from their back catlog is rather misleading given that they have re-released a large number of their older titles to either buy or rent on every console since the Wii, along with releasing mini versions of their older consoles with the titles pre-loaded. It's not like they locked those games away never to be seen again.
