How it's advertised likely has NO correlation with how it's used. This product is for piracy.
thats same for anything.
The legit reason can be the main reason even if its the least used one.
Nintendo restricts backups to their subscription model...and even IF you do pay for it some games do NOT let you backup at all. (pokemon games are example of this due to risk of abuse of trading, then reverting and basically cloning pkmn), Back on the 3ds w/ I think it was pkmn x/y many people were shafted by a bug in game that bricked your save if you saved in a major town.
This happened after the evnt for a 1 time obtainable item....meaning peopel started over and lost out on ever getting that item again. The fix for it didnt come for like 2 weeks (and no mention of it ever beign fixed so ppl never were aware to not start over).
This is why some people like having backups in event a game comes a game breaking issue.
Piracy is a grey area at best.
If I buy my console, the games, & I obey every rule about not cheating....is it piracy?
If you bought a game, it dies from age, is no longer made, gets stolen, or some other accident happens that its not playable anymore is it piracy to dl a rom of it? you paid them for the product so does it really matter how you play it so long as you paid to begin with and arent sharing it?
Yes, Piracy is a big issue, however it isnt black & white as there are grey areas.
I am a big Nintendo fan. Owned every console (except the virtual boy), some multiple of each, from og gameboy to the Switch 1...only reason I dont have a switch 2 atm is no exclusively switch 2 games I care about atm...I'll likely buy one in future though.
I like the products (if its one thing i will always defend Nintendo for its they are one of only game companies that try stuff out thats different even if it will fail) and I know devs of games don't make the anti fanbase choices of the company so I enjoy their games.
At the end of the day people like me who do support and buy stuff (even when every generation of Nintendo consoles have been easy to pirate for over a decade now) still out number the people who pirate it illegally.
Has anyone been banned for copying a game and running the single copy with the originals safely stored away?
we won't know that answer most likely.
From my udnerstanding its server seeing a game carts specific data being used by multiple systems in a period of time thus triggers that specific games id to trigger a ban.
Apart from that the device detecting a flashcart device "could" get you banned i guess but again we likely wont know.
