Nintendo really needs to make a Netflix-like service. I've said it since the Wii U started to collapse.
I'm pretty sure they can make more money with a service instead of charging $4-8 a game. Something like this:
$A a year offers all NES games available
$B a year offers all SNES games available
$C a year offers all N64 games available
Make a special bundle where it's $X if you buy all three together.
