Even when Nintendo actually sold the games, people found (legitimate) reasons to not buy them anyway.
On the Wii, games sold in PAL regions were 50Hz versions, unacceptable in the post-5th gen era when Nintendo offered 60Hz options for most of their games, even before Sony started doing that.
On the WiiU, N64 emulation was botched, with games looking visibly darker than on the Wii VC.
And on top of that, you had tons of people complaining that they'd have to rebuy the games every time Nintendo put out a new console.
Meanwhile, all the people complaining kept not buying the games and emulating them elsewhere anyway, with better results.
So… why would Nintendo try to sell the games anymore to people who kept complaining and not buying them for a decade?
What people mean when they say they'd rather buy the games, is that they'd buy NES and GB games for $0.99, SNES and GBA for 2.99, N64 for 4.99. I can assure you that nobody would put their money where their heart is when a NES ROM is sold for 5.99 at the very minimum. And then you see GBA Pokemon games sold for fucking $20 and… seriously, nobody can say they'd rebuy these games at Nintendo prices and believe it. So don't expect me to believe it.
