If you're on Android, a modern phone from the last 4-5 years should be able to play almost everything from Atari to PS2, and stream PC games if your network is fast enough. I've had a Shaks and Gamsir stretchy controller for my phones and it's fucking awesome, haven't had any issues with lag or connectivity
Synced saves with my PC so I can play Burnout or Tony Hawk on my PC and pick it back up on my phone, with RetroAchievements to track your progress if you care about that
You can set up a frontend like Daijisho, Dig, or Beacon to see all your shit nicely in one place in a controller friendly UI
It's pretty tits
