It's reported that the Google Play store entry of Eden emulator (a Switch emulator) is no longer available. We don't know the reason, but my educated guess is that Nintendo might have striked. I recommend to download current official clean builds and source code for backup, just in case you want to use it later.
I personally still use last official build of Yuzu, even today (playing Tears of the Kingdom). I never tried Eden, but it might be useful to archive it, so I do not need to download builds of others if I can't build it from source for any reason.
