I installed the Moonlight VPK, made a server.txt, paired it to Geforce, made a settings.txt, and lowered my PC resolution to 720p for Steam to load on the Vita. But the physical buttons don't do anything in Steam Big Picture Mode, nor when a game is loaded up. Touchscreen stuff works A-OK, yet pressing buttons doesn't do a thing. What did I miss? Can someone please help me? Thanks.
