So I was looking earlier at custom/DIY stuff I can add to my rig whilst I wait on my wheel replacement and I found someone on PCars forums who had the idea of using a numeric keypad as a cheap and efficient button box that works on PS4. After mentioning it to a couple of others here that I might know a guy who could make up some good quality decal sheets for them I thought it might be an idea to ask if anyone else is interested in a bulk order on the decals. Here's the idea: http://forum.projectcarsgame.com/showthread.php?33122-Button-Box-on-PS4/page3 I'm thinking of a sticker sheet with all of the assignments would be the best way to go. That way people can mix and match as they like. I've ordered a $4 keypad from eBay to test it out.
