thanks
ok i don' have any spare resistor(75ohm) on my hand right now.
Here other test i did.
1. Unplug the keyboard, plug the joystick, the guy is going straight down by itself.
2. plug the keyboard, unplug the joystick, the guy is going to the bottom right by itself.
3. remove the 558 chip and test with the keyboard only connected, still going by itself to the bottom right?
then now im confused lol
