Good NES/SNES/PS1 emulator console

Looking for a good retro emulator console that comes pre-loaded, you know, like the ones you see all over FB/Amazon that say 600 in 1, 15k+ games, etc. We bought an NES/SNES one that claims to have thousands of games, but a vast majority of them are weird Japanese alternative versions of mainstream games, half of which don’t even work, like they were someone’s unfinished pet project. Plus it doesn’t save progress.

Not wanting to buy a console/device and turn it into an emulator, just looking for a simple retro emulator console for my kiddos to play some of the old school games I played growing up.

Any advice? Thanks!
