The suggestion on keeping a separate SD card just for emulation is great! I have an extra SD card, ready to do this. Do I just need to install EmuDeck (on the SD card itself) and then add ROMs to it and it’s that easy?
Also, as a follow-up question: do you know if using FileZilla/SSH is possible to transfer files between a Macbook and Steam Deck? I have a PC, but it is admin-locked via my work. But I’m trying to figure out the best way to use my personal Macbook to do file management with Steam Deck.
