Hi, I have a question about arcade sticks, I have an arcade stick made by me and is something I’ve noticed that response time, compared to my keyboard has too much (the keyboard is to press and instantly make the action) could be the fault of pcb that is not of good quality? (I use a pc gamepad compatible PC/PS2)
Thanks and best regards
And now you want to let us guess what kind of PCB you’ve built in? 
-> look over here: Is there such thing as a lag free PS1/PS2 to PC convertor?
