Old games made for machines with 4 way joysticks (PAC-MAN, Frogger, Burger Time) just do not work well with 8 way joysticks. For example, if you're going diagonal up and to the right, the game doesn't know if you mean up or right. This is actually a physical problem. Maybe someone has figured out a software patch to guess based on the first position you hit on an 8 way joystick, but I haven't seen it. I simply added two inexpensive 4 ways (the red and blue knobs) wired up to the same controls as the P1 and P2 8 way joysticks. PAC-MAN hasn't played this good since the original!
