Steam now supports rebinding controllers for free via Big Picture mode. Let's go over how to do that.

At the top of your steam browser, look for a box with arrows pointing to the sides. Click it to enter big picture.






Now that we're in Big picture mode, click the gear the top to enter Settings, then click Controller configuration. (Or, whatever controller you're using.)










With that done, head back to the main menu. Go to your library and select Pac Man Championship 2, Manage game, then controller configuration. Now you should see all the buttons you can mess with. Click on the box for your left analog stick.











There's a lot of stuff to mess with here, but we'll simplify it. First click "Advanced settings" at the bottom. For Style of Input, select directional pad, and Layout will be "4 Way (No overlap)." For Up left down and right, you'll be using the Dpad equivalent of each.

Here's a picture to show the settings:






Once finished, click Back at the bottom, then Done. This should be enough to enjoy Pac man DX properly again.

Xpadder is an application that allows you to bind keyboard commands to your controller. With the latest update, which Bandai Namco has refused to fix, you'll find that the sensitivity will be messed up on your controller. Xpadder will help get around this.

Keep in mind that my version of Xpadder may be different to yours. I don't know if xpadder recognizes PS4 controllers, but if it does you can still replicate these settings since the Xbox 360 and PS3/4 controllers are similar anyway.

• Bind left analog stick to arrow keys.
  
• Bind dpad to arrow keys.
  
• X to X.
  
• Z to Y. Alt to Y. (For brakes.)
  
• Backspace to B.
  
• Enter to A.
  
• Escape to start.

Next, click on the gear for left analog stick, then settings.


Take a look at this image, and replicate what I have here:


This is everything. IMPORTANT: When you start Pac man, press ENTER on your keyboard, and you'll be able to play reliably with your controller again (hopefully). This my first and only guide, it's probably awful and ugly, but I hope it helped you out.
