Where is the service switch, and how do I activate it? There are 2 buttons and a volume control inside the coin access. One of the buttons is labeled credit (it is the free credit switch). The other buttons isnt labeled and so far it does nothing...
Help please,
Thanks,
Greg
 
Earth, wind, fire, water. NSS owners unite. We are Captain KLOV. lol. Seriously, how do I activate the service mode?
 
I'm not at home or I'd tell you for sure, but I'm pretty sure that other button is what you need. I'd verify that it's hooked up properly. It may need to be held down while powering up, or pressed only while at the title screen... or something strange like that. I know there's a scan of the manual around somewhere online, but I can't find it ATM.

Sup Dog!
I tried tuning the game on while holding the switch in, but no service mode. Also, I tried holding the switch and the reset button in while the game was on, but no service mode. I am starting to think the switch is wired wrong or the switch is bad. I will continue trouble shooting, but it would be assuring to know I am doing it right.
Thanks guys,
Greg
 
If you don't figure it out by tomorrow night... drop me a PM to remind me to check.

I'm back home and I just checked... you need to hold the credit switch while turning the game on, or hold the credit switch and press the reset button on the control panel.

Thanks again dog! You were right again. I wonder what that other switch is; the one next to the credit switch...so far it does nothing. I have tried pushing it in many different combinations, and it doesn't activate anything??? Anyway, your the man!

The manual says that other switch is not used... it's a JAMMA cabinet, so the switches are probably service and test... and it apparently only uses the service switch.

Thanks for posting this. I always tried the Service switch and Reset button and got nothing. Now I see it was supposed to be the Credit switch and Reset button.

Where can I download the manual for the Nintendo Super System? I've searched and can't find anything.
 
I'm not sure... I think I found it once before, but I have an original that was in my cabinet that I just looked at.
