Meanwhile people with hacked Switches are already playing them. I don't understand companies.

Yeah this doesn't make any sense. Just hire a small team to update and get older games running on Switch. Then put them up for sale in the eShop at a discount. Finally, make sure the eShop is continued to the next generation of Nintendo systems until the end of time. Anything older than Wii should be a $5 game tops. Nintendo would make millions doing this.

It doesn't make any sense why they shut down the VC, instead of just bringing it over entirely to the Wii U, and then the Switch.

The people with hacked Switches represent a negligible share of Switch owners.  Also, to be blunt, the majority of those people were never going to pay for legacy games in the first place.  

That's not my point. My point is that people can get retro games running on every device under the sun, sometimes in a matter of days. It should be a doddle for Nintendo yet they don't do it. Neither did Sony with PS1 on PS4. I understand third party games would require contracts/agreements or whatever but their first party games should have been up ages ago.

Don't know what takes these companies so long.

Snes, GBA, GB, GBC and N64 games are all playable on the Switch with emulators, why can't Nintendo themselves do it?

Nintendo is just dropping the ball on this one. No reason not to put their SNES, N64, GC and Wii titles on the Switch. At the very least offer collections like Mario 64, Sunshine, Galaxy 1 and 2. Do something. Nintendo is sitting on a treasure trove.

Yeah 1-5$ for nes-gc games from nintendo.
Then charge 10-15$ for the Wii-WiiU games.

Sadly Nintendo never does that sort of thing....

I think Nintendo sees compilations, remasters, and subscription models as the way forward for its older titles. Still, I don't see what's taking them this long to get more of its back catalog out. I at least want SNES games this year sooner or later.

Of course they *can* do it.  After all, they've done it before.  This isn't a technical question, but an economic one.  Nintendo is clearly of the mind that subscription is going to bring in more revenue than a la carte sales will.  We would all like to see them add games to the subscription service at a much faster rate, of course, but it's fairly obvious SNES titles are coming around the time year 2 renewals come up for NSO.

Meanwhile the Nvidia Shield TV, also running on a Tegra X1, has official 1080p Nintendo ports of Mario Galaxy, Twilight Princess, and Donkey Kong Country Returns... only in China.

This is very forward thinking of Nintendo, by keeping rentals to one game at a time, they won't have to spend so much on restocking the eShop and it'll force gamers to try out new titles they might not have even heard of. If all 15 copies of Super Mario 64 are on rental right now, no problem, put your name down and now you have priority when a game comes back into stock. In the meantime you can rent Tonic Trouble and if Mario 64 is available before your rental period is over you can cancel the remaining time on your current rental and add those hours/days onto your new game, up to an additional 2 hours playtime or 5 days of rental time.

Sony and Microsoft will be struggling to restock their digital Halo and Uncharted games to keep up with demand as users abuse the ability to download multiple titles at once, while the less popular titles remain completely untouched. Nintendo, on the other hand, will be making smart use of its full library and teaching its customers the value of patience and opening their minds to new experiences.
