It hasn’t even been a day since the Nintendo Switch Online service launched, but hackers have already managed to get into the service’s NES emulator. In fact, hackers have already figured out how to replace NES games and add in new ones. According to kapu, who discovered this information, the service’s NES emulator is nothing more than “a quick port of an existing emulator packaged with some ROMs”. The “existing emulator” that kapu is referring to is the NES Classic Edition, which was already hacked a while ago.
Kapu said to Polygon that “for someone without prior experience in running Switch mods, getting all of it set up at first is a bit of a process, but nothing too hard with proper instructions. After an initial setup it’s insanely easy to swap out ROMs and add entirely new ones”. As for why the emulator seems to be so easy to hack, kapu says that “I have serious doubts that it points to any vulnerabilities, I’d say it’s just a side-effect of making it easy on them to add more games as they officially release more, thus making it easy for modders as well”.
