Ah ok, 20 years seems fair. I wonder if Nintendo is concerned people would rather play old emulated games for free instead of buying new (expensive) games.

Or are they planning to monetize these old games at some point? Imagine if they provided a monthly subscription to a library of emulated games for Switch. Playstation does this in the Premium subscription layer.

Anyways, if they are going after people emulating 20yo games, that's pretty unreasonable. That's some penny-grabbing shit right there. How much people actually emulate games anyways? How much people want to play 20yo games anyways? I can't imagine that being any kind of threat to their income.
