Has anyone else had any luck using the Steam Controller with MAMEUI64? No matter what I try, MAMEUI does not recognize any inputs from the Steam Controller. I launch MameUI64 through Steam big picture mode as an external program and have tried both Keyboard + Mouse and Gamepad profiles, but MAME does not recognize any inputs when I bring up the MAMEUI Input menu, using tab in MAME. The strange thing is that when I am in the input menu, I see a second dimmer yellow bar scroll up and down in the background when I use the right mouse pad on the steam controller, so Mame is reacting to steam controller inputs in the menu screens, but just wont recognize any inputs on the input config screen. The steam controller is also working fine as a mouse to select games in the MAMEUI front end. I did briefly get it to recognize the steam controller arrow key inputs in the input screen at one point after plugging in and unplugging my joystick / steam controller in various orders, but haven't been able to replicate this again and the controller still cant be seen.
I have tried with the Steam Pad connected directly to my PC using USB, as well as connected to my steam link and both don't work. I have tried with the "multiple keyboard" and "multiple mouse" options both on and off (I have a Logitech wireless keyboard and XBox 360 wired controller hooked up as well) and this doesnt work.
Has anyone else managed to get MAMEUI working with Steam Controllers or have any suggestions on how I can get mine to work? Thanks.
