Nintendo is currently registering a new technology patent to identify cheating players like Mario racing 8 and Sprague 2. In fact, manufacturers of multiplayer game business are studying the problem of anti cheating software, trying to provide players with a fair game environment, and now Nintendo seems to plan to solve this problem by itself.
Nintendo wrote in its application to the U.S. patent and Trademark Office: "when the game scene extends to multiplayer games, cheating will become unexpectedly common. Specifically, users can modify the software to gain an advantage over players on other machines in multiplayer environments."
Nintendo's new patent will use a technology called "code reuse" to automatically generate an "authentication program" to identify whether the game has been modified. According to patent information, this technology makes it easier for companies to determine whether players are running modified games remotely.
I don't know the specific operation mode of this technology and the advantages and disadvantages of anti cheating technology compared with other games such as call of duty, but Nintendo has always been blind to sand, so once they make a move, they mostly come for real.
Now "Sprague 3" is about to be officially released, and Nintendo's patent should also be prepared for a rainy day.
