Ryujinx still exists so, besides android, switch emulation is still going.

Subs are your friend. I studied Japanese got over a year, but most of my vocabulary came from animes and games. Try to find some Korean shows that might interest you. If you are into games, some mmos have Korean voice overs. Korean alphabet is simpler too so it should be a lot more effective for you. Still, if you need to practice reading Koreans make a lot of good webtoons. Finding originals may be a bit harder but give it a try.
