what issue does it give you? does it not recognize it at all? or is it too sensitive and keeps reading one of the axis all the time? if its the second one, it is doable. when setting up the pad, it would always read one of my axis. you just have to be patient and keep hitting the button or axis you want to it to read. for example, if mapping the brake, keep hitting "map" the brake with your foot on the break. itll take 5 or 6 times but it will finally read the correct axis, same thing with buttons. it all about timing.
Ive got a good setup and faster than speed still hiccups from time to time. maximum speed i dont play because i think its weird. you go from 0 to 200 in a second and when you turn more than 5 degrees, the tires screech alot. it get annoying. i couldnt find a video of the gameplay of the actual arcade version so i dont know if its just a poorly made game or if the emulator is messing it up
