They can only detect a modified save if it fails their sanity checks. meaning it has something not possible to get in game. (too many master balls, pokemon with impossible levels, spiritombs with wonder guard, etc.)
I don't think nintendo can tell the difference between a retail cart with cart header and a digital copy with console header.
What they CAN do.
1)Detect a shared cart private header. if its' used enough, everyone involved gets banned, except maybe the very first to use it.
2)detect going online before the release date. but they have to plan for this. they told reviewers NOT to go online because they were planning on banning EVERYONE that went online before the release date.
3) booby trap pre-release software. it's simple. make sure versions before the final don't respond properly to an online challenge. this is why i will not trust the leaked dump. This does not affect their testing because they can unban themselves.
They CANNOT seem to.
1) be able to tell the difference between a cart header and a console header. because of this, cart headers shared between different games are not considered suspicious. only if they are shared between copies of the SAME game d they catch it.
2) detect digital copies of games NOT ON THE ESHOP. this is related to 1 above. if they CAN tell the difference between a digital copy and a cart, they'd ban everyone who played a cia online that's not available form the e-shop. and they would be SAFE in doing so, as digital copies that can't have came from the shop MUST be dumped or downloaded, and nintendo considers that piracy. the fact that they have not proves they can't tell.
