It’s just drag and drop files in a folder. No other outside sources
I LOVE portable consoles as I can’t just play on the TV because it’s in the living room so I’ll let my gf have the TV. Plus having all my related games on one divide that I can easily transport with me was a no brainer. Steamdeck has topped the switch for my all time favorite portable console.
I loaded up the game but I can’t move lol
