It’s apparently easy to load your own Roms into the Switch official NES app
Hacker KapuccinoHeck has shared some findings about the new NES emulator that is part of Nintendo’s new “Switch online” offering. Apparently, it’s fairly easy to load your own Roms (on a hacked Switch) and play them directly, which the hacker demonstrated by loading Kirby’s Adventure (video below).
The proof of concept work is currently done by simply swapping the Roms of the games on the device. The hacker stated that the games are simple .NES files that can easily be swapped.
Furthermore, KapuccinoHeck mentioned that the NES App on the Switch seems to be a hastily created port of the NES emulator running on the NES Classic, Hachikachi. Because of that, there’s good hope that tools will be made available shortly for people to easily increase their NES library on the Switch’s own emulator.
In the meantime, Rom swapping is allegedly easy if you already have a hacked console (we haven’t tried yet). Or if you really want your NES fix on the switch, you can also give a try to the fceumm emulator via Retroarch.
