The repositories are not updated, so, when I try to download the emulators sugested for 3ds or switch, it takes me to the yuzu/citra playstore, but It is no longer available, so I can not play 3ds or switch.
Citra and Yuzu have both been shutdown a few months ago. They both have quite a few forks though, try using those instead. As for which is best that's for you to decide.
