I say both! The right joystick is better then the left. No cheat here !!! Why you talk about unfair tactic ? Maybe its my english wording?
Anyway, i move my right joy to left, without moving the micro switch. Same behavior. So, next step it s to fix the microswitch. No special tactic, just hardware improvement. My arcade is 10 years old, she need some affection.
Right now, the diagonal movement is very hard. So, 45, 130, 225 and 325 degree are difficukt to get!
