If that is the case, then sure they could be running them on Dolphin in the remote server, I don't think there is any law that prevents that given the GPLv2+ license. Only if they happen to make some change to the emulator source code, they should publish those changes, but who says changes need to be made?
with three Nintendo games pre-installed: The Legend of Zelda: Twilight Princess, New Super Mario Bros. Wii, and Punch-Out!!. All three games were originally available for the Wii nearly a decade ago at a measly 480p resolution. According the Ahmad they now run on the much faster Shield at what should be a nice and crisp HD resolution—meaning 720p or 1080p.
Honestly, I more want to play these games on Switch instead of Shield. Nintendo has never released wii or wii u in our country. Now Switch has support Chinese language(though imperfect), but should we buy another machine to play them?
