I may have found a fix for this just now. The tl;dr is if you haven't used the core that your game is running from before, you need to configure your controller for it in RetroArch. The longer story is I was attempting to play a NES game from my Steam Link using Retroarch (NEStopia) via Big Box with a PS4 controller, and having the same problem where the controller worked for everything but the game. I found I was able to get to the RetroArch menu by loading the game up in BigBox, then hitting my RetroArch menu combination (L1+R1+Down+Square), then I scrolled over to the History area of RetroArch and found the game I was attempting to play. When I selected the game, I was able to either Resume, or do a number of different things. I went down to the Controls section and changed "User1DeviceType" from "auto" to "Gamepad" then backed out and re-hit my RetroArch menu combination (R1+L1+Down+Square). The game went back to normal and my controller worked. So here's my step-by-step fix. Load up a game via Steam Link > Big Box > RetroArch Hit your RetroArch menu combination on the PS4 controller (L1+R1+Down+Square, or L3 + R3, or Select + Start, etc.) Move over to the history section and find the game you currently have paused in the background Select the game and scroll down to Controls Change the "User1DeviceType" from "Auto" to "Gamepad" (Optional) Configure the rest of your controls from this screen Back out to the main RetroArch Menu Hit the menu combo from step 2, and play the game.
