Can someone tell me which controllers work for this game?

I think controllers with Direct Input work the best with the game, like Logitech F310's. I use a Playstation 4 controller with the game tho. Works fine but the d-pad doesn't seem to work with it.

Yep, this game predates Xinut, so a Dinput controller works better. I have an F710 and it's just fine in Dinput mode, you can push use all of the buttons and dpad, unlike an Xinout controller.
