And to think Nintendo wants these to end up in a landfill. Imagine if jailbreaking video game consoles (that is, modifying hardware that you own however you want), were actually legal. Old consoles like these could continue to provide value to owners via competing app stores, free and open source apps/games, cool hardware features like the OP, etc. All of that could happen without infringing on Nintendo's rights, or…
To that extent that Nintendo has any influence in this area, I'd say they're quite supportive of people using their old hardware. Many Nintendo games display discontinued devices prominently (WarioWare, Animal Crossing), and there are stories on Twitter of Nintendo phone reps helping troubleshoot NES and SNES hardware issues. Nintendo won't support people pirating their games , but as much as I think copyright lasts…
Nintendo is a member of the Entertainment Software Association (https://www.theesa.com/), which AFAIK is the main entity lobbying to keep console jailbreaking illegal.
Not to mention the fact that Nintendo shuts down online services and digital stores for old consoles, which means that you can't even download games you've purchased anymore.
Also, the issue isn't about whether Nintendo wants people to play old games on old hardware, it's that Nintendo doesn't want you to play new software on old hardware, and that they're actually able to enforce this through the DMCA's arbitrary special restrictions for video game consoles (by comparison, jailbreaking phones is perfectly legal under the DMCA)
That both suppresses competition, directly hurts consumers, and is just wasteful.
