Quote from Can You Watch Videos From an SD Card on Nintendo Switch?
There is an unofficial workaround to the lack of a decent media player on the Switch. This involves using something called custom firmware via the Homebrew App. Be warned. This falls under hacking within Nintendo’s terms of Service, and may result in a ban. Being banned by Nintendo means that you’ll no longer be able to access the official servers and this may affect a lot of online games.
Although this method may work for some versions of Switch, it’s often patched out by Nintendo. It also won’t work with the Switch Lite at all. This method is unadvisable, as not only may it not work with your console, it voids your warranty, and may result in an outright ban.
If I install any software from GitHub on Nintendo Switch, may I no longer be allowed to participate in online games / get a ban?
Is installing Cpasjuste/pplay legal in Nintendo terms?
Installation Switch: copy "pplay" folder to switch sdcard ("/switch/pplay")
Excuse the possible stupid question. I'm a fan of GitHub and co, but don't want to risk invalidating my device. Would be very happy if someone explains to me what I can and can not do with installation of software from sources other than the official store.
