Hey Jeekay, can you confirm what version of the software you are using on your STPRO and if the super skill shot works well? I too have the same 1.61 modded rom but have never used the skill shot so I did not notice until Kronnix pointed it out. I was on the unmodded 1.60 previously. Thanks!

Bump - Can STPRO owners with the latest 1.61 unmodded code, confirm the super skill shot (holding the left flipper) when plunging lifts the gate to complete the orbit?

We need to verify this works, before assuming this is a modded code issue. Thanks for your help pinheads!

Thank you for the feedback. Dagnabbit, looks like I am loading the unmodded 1.61 code back onto my pin to test this feature Could this be related to a fuse issue? I need to dig out the manual and check, because I have not had this functionality on my PIN at all and I have always had a modded 1.50 BIN installed when I got it in a trade.

Update. On modded Bin, I tested the coils 51 and 52 (left and right) but neither seemed to open the gate individually, I had to use cycle coil test to actually see #52 working. So it does appear to be working in diagnostic, just not in the actual game. Interesting.

Ok, this is getting weirder. To make sure, I went to the Stern site and downloaded the 1.61 code for the Pro and flashed it back this AM. In testing the skill shot in game it still does not work. However...

In diagnostic testing of the coils:

#53 Vengeance Ship Coil - testing this actuates the Left Orbit Gate!
#52 Orbit Gate (Right) - actuates the Right Gate as expected
#51 Orbit Gate (Left) - actuates the coil on the Vengeance Ship!

Ok, what the heck is going on here. Can an STPRO user with the latest 1.61 STPRO rom test if they have the same behaviour in the coil diagnostic menu? Could this be a botched fix or mistake made in production? I am going to crack open the manual and try and trace those coil wires to the boards and see if they have been swapped by some wannabe pinball repair dude.

Confirmed, in game, when I hit the left flipper for the skill shot in game, the Vengence Ship coil does actuate! . So I am bit confused here. I am going to flash back to the modded code. If you guys think I am nuts I will be posting a you tube video shortly of this oddity.

hey Kronnix, I have had a bad head cold this week so my attention to detail is severely lacking. I have gone back to the modded code and have the same issue, I do in fact have crossed wires on coils #53 and #51. For some reason I never noticed this before which speaks to my attention to detail in general (sad). So it appears that my issue with super skill shot is not related to the modded code IMO.

It was a coincidence that we both noticed the skill shot not working at the same time hence we blamed the modded code since that was the common factor.

You may just have a bad coil on #51. I would go with that explanation for now.

I swapped Q51 & Q53 wires on the 6-Transistor driver board and my skill shot and Vengeance ship are working fine now with the modded 1.61 code. Issue resolved on my STPRO.

Hey dude, I think the wires being mixed up was unique to my STPRO, I cannot see that being the issue with your PIN especially since it was working fine before for you. This could be a bad mosfat/transistor issue that needs to be replaced for Q51 on the 6-Transistor driver board that controls that coil. Any electronics shop can test and replace it for you if you do not have the soldering skills. You will have to remove the mini board and unplug the IC's to get this fixed. I believe you may also be able to order the board directly from Stern (call your local Stern dealer) and just swap it out. Are you still under warranty?

FYI: To test a coil, you push the black button. You also have to make sure you pull out the coindoor detector (It pops up) so it will turn back on the high power voltage with the coin door open.
