While DmC and Devil May 4 worked just fine, Devil Cry 3's Controller support was piss-poor when I was trying to use my 360 controller. Which is why I had to fix it, it's works just fine now. I made a guide to show you how to do it yourself.
Now that I don't have to worry about that anymore it's been great, I just wanted to share my knowledge and save you guys some time. In the end all 3 DMC game off steam work fantastically now and I found it to be a great deal for $60. I hope the guide helps those that need it and have fun.
Update: I'm also willing to help anyone with issues. just send me a PM.
