MAMEWorld Forums - Hardware - How to emulate Xbox controllers for Steam on an arcade cabinet

I'm building my first arcade-style cabinet and am aiming to play Steam games using arcade controls. Unfortunately, I can't seem to find a solution where I can control games easily in Steam.

My thought is to remap my controllers to 4 xbox controller emulators. Ideally I want something where I don't have to remap buttons for each game, but will instead always treat it like an Xbox controller. So the solution doesn't have to be my direction below. If you have a diff solution that gets the same results, I'm all for it!

I have been messing with x360ce, UCR, etc, but my main problem is that they ONLY see the keyboard OR the joystick. I need to combine them both for each joystick.

In Steam Big Picture mode I have tried to go to Controller Settings where I can see the Ultrastiks, but again, I can't add button presses. They will only recognize stick movement. Likewise I can see some of the test controllers I make, but they are either ONLY the joystick or ONLY the key presses. in x360ce I can only use the keyboard once, and not at the same time as a joystick even though I can add both profiles to one controller.

my setup: x4 Ultramarc Ultrastiks with 2 IPAC Ultimate boards driving them - Win 10 PC. The IPAC's remap the buttons to keyboard presses, all of them map to 1 keyboard.

Any help or direction will be greatly appreciated!
