No, what he is asking, is how to walk like he did at the begining, and the answer is that you need an xbox controller, I have one and you can walk when you only just push on the stick. And for this to work you need a Controller Emulator, I also have one, If you check some of my vids on youtube, I think I have one where I use an Xbox controller. ( Xbox Controller to PC 1.2. )
Search something like that on Amazon and see if you can buy one. It's good, and helpful.
Hope I helped.
