I haven't followed the Switch scene because of how toxic it is in its current state. Also, no money to buy a Switch lol. The 3DS suits all my needs.
I don't know how the process works, but it's supposedly possible to download games from the CDN server for the Switch by sacrificing other Switches to act as some sort of middle man. Those Switches eventually get banned when Nintendo sees too many downloads coming from them.
I'm not familiar how it exactly works on the Switch, but I don't believe this process can be applied for the 3DS.
