Title pretty much sums it up… Also, I installed retrodeck on the SD card that I’m also handing off to him, can I leave just that there for him? Will retrodeck just work once he logs into the steam deck? Anything he needs to do besides log in with his account on the deck? Thanks for the help!
I suggest a factory reset. (Which will remove all your stuff).
He would have to set up retrodeck or whatever again after logging in anyway.
Why would he have set up retrodeck again? I think retrodeck is a self contained installation on the memory card?
Most are, but some are in your users home directory and that is unique to each user.
