While we often say that Nintendo’s patents may never get implemented in games, this one in particular seems like something Nintendo would want to include in all of their online-enabled games going forward.
Nintendo is always out to make sure people are playing legitimate copies of their games for numerous reasons, cheaters included. That’s why it’s no surprise to see Nintendo file a patent related to hunting down players who are using modified versions of their software.
In particular, this patent is for attestation programs that employ “code reuse” techniques, which would certainly hunt down a healthy amount of players who are running games with nefarious bits of code/programs attached to them. If this kind of software is detected, it’ll be shut down on the spot. Thanks to regular checks while the software is in use, this approach should be able to spot issues as they arise.
We don’t know when Nintendo will implement this patent, but hopefully we see it put to good use in Splatoon 3 and all Nintendo titles going forward.
