funknflow5200 Posted October 24, 2015 Share Posted October 24, 2015 so I got a 7800 the other day that was in pretty rough shape, had to swap out most of the switches to get it to work ( pause button is still faulty). the issue that remains is this: when playing 7800 games that require two buttons, the fire buttons on the joysticks do not work. games that require one button: fire buttons work fine. on atari 2600 games everything works great except my paddles will not register movement. has anyone had this issue? I'm at a loss. I reflowed all the solder on the controller port. maybe I just need a new motherboard? help! Quote Link to comment Share on other sites More sharing options...
+DrVenkman Posted October 24, 2015 Share Posted October 24, 2015 (edited) I believe the TIA chip registers paddle movement as well as the triggers for joysticks. The 7800 (again, going from memory) can use two fire button on the joystick by using a combo of the paddle input signals for the second trigger. With the combination of problems you describe, that's where I'd start troubleshooting. Edited October 24, 2015 by DrVenkman Quote Link to comment Share on other sites More sharing options...
