So I picked up a 555 timer from radioshack and threw together a (freeform) 555 timer rapid fire controller on a matrix board. I planned to use it for MW2. I was able to install it and it worked fine with a push button, shooting it just how i wanted it to. The problem i have with it now is whenever i shoot with rapidfire (press the push button), I can no longer use the thumbsticks buttons (not the actual thumbsticks, but i cannot click the left thumb stick or right thumbstick). In other words, after i shoot one bullet with the rapidfire controller, i cannot run or knife in MW2. I was wondering if this is normal with the 555 timer mod, or is it just something i did wrong. Also, whenever i pick an automatic weapon, it shoots automatically without me even pressing the push button, and there is no way to stop it.
Anyone have any ideas as to what's the problem? Any help would be greatly appreciated !
