S2000 Triple Diamond - Pays Incorrectly on Certain Combinations

[gordonslots]

I have an issue with my S2000 Triple Diamond machine where it seems to payout certain combinations incorrectly. Its not on all combinations, I would say majority of the combinations it pays out correctly, however there are certain combinations like shown in the picture I have attached that pay out when they shouldn't.  There's also certain combinations that don't pay out that should.

I have went through and checked the reels to make sure the notches are matching with the notches on the reel strips, is there anything else that could be causing this issue?  Machine operates just fine otherwise.

Thanks for the help in advance!

there are several possibilities. One, the base rom is wrong. Two the strips are wrong, and three, you have slant reels in the machine instead of upright reels.

Agree with hotlsot. What is your sb game chip number?

For Triple Diamond 2 credit 3 reel, 2500 top award, I found this SB game chip number :

SB100064 or SB100559 or SB100831 or SB101004

There are AAA and ABC strips for this game, the SB/SS has to match the strips.  Strips may just be in wrong order also if ABC strips.

He won 4 credits, he should have had a cherry on the reel strips

S2000 slant and upright reels are the same the strips get mounted up side down on them and the machine knows to run them backwards if it detects a slant cabinet. And holy crap i just realized why machines with a total loss of senet data spin the reels backwards on boot. Cabinet id detection is handled by the 5 button deck harness so if senet fails it doesn’t know what cabinet the board is in and defaults to the inverted spin of a slant.
