Double Diamond Mine Sound Issue - Expert Required

[jdkmunch]

I need someone who knows this game-  From what I remember it should not sound like this -   

please listen - listen carefully to the sound as the reels are SPINNING two or three times-  it sounds scrambled -  the notes don't go together

If anyone has this game -   IS THIS NORMAL?  I cant believe that it is  -  i don't remember anything like this ever in the casino

Pull MMLB board, remove SIMM and clean it's fingers with an eraser.
Blow out socket with canned air and inspect fingers.
Reinsert SIMM a few times and reboot the machine.....

Sounds like "Bad" data to/from the SIMM. That SIMM has a LOT of sounds NOT
used in a lot of the games.....

MMLB?

I don't know what this is? 

sorry <felling under educated >

[jdkmunch]

Kirk did you move yet? When is the big day?

[KirkLasVegas]

Moving Mid-January Looking forward to it.
The "Vision" games use differant configurations. Some use a MMLB (Multi Media Lite Board) and some get the audio from the top display computer.
The "MMLB" is a piggyback board that sits upside dowm on the main chassis on a pair of long white sockets and held in place by 2 screws.
I don't have any 504's and MMLB's to take a picture of to help you....sorry...

ok same MMLB that goes on a 3902 or 044 i guessing -   this game has no such board on the MPU

It must all come from the top lcd box

Hmm,
in a similar vein (like using an eraser on Simm card "fingers". I think these are called the card contacts actually. ),
try re-seating the CF flash card on top of the LCD unit.
It may have a bad sound pin contact?
The sound files are in a folder on that CF card.

[jdkmunch]

but you agree -   something is wrong



correct?

[stayouttadabunker]

but you agree -   something is wrong
correct?

Oh definitely Munch!
I'm really suspecting a very slightly corrupted CF flash sound file that is missing a byte or two
and that's what's causing the skipping sound.

or


a dirty pin that connects to the CF card up in the slot of the LCD computer
 that is directly related to the sound file path.

[jdkmunch]

Here's what's interesting -  the MPU has a sound wire out - that goes into the LCD top box line in.  

Then the lcd top box has two speaker wires out.    If I plug the MPU sound wire out directly into a speaker - I hear every other note!!!!    It's only 1/2 the sound!!

Then when I go through the LCD box  --  It's complete - meaning there are not gaps in the audio, however the notes just don't match up.

 

[jdkmunch]

I disconnected the audio wire from the MPU to the LCD and now there is no reel sound whatsoever.

Even the button dings are gone.

This points me to MPU right?    is mpu is generating the sound for the reel spin-   or the lcd box -  from my experiments it seems that it's the mpu

Oh! I got it! Well...partly...haha!
You're "splitting" the audio output!
How to fix that is best left up to an audio expert that understands
the audio amplifier circuit board in the back wall of the topbox.

I think Foster was playing around with that.
Also, I know that Idesign had some sort of an audio jumper somewhere to get better, even sounds.
There's a thread somewhere about that.

I think it was posted in Yoeddy's Simm testing threads and I think Foster figured out that it worked for the Vision?

This is all based on my CRS memory bank...it's never fully functioning correctly -
due to over 11 thousand posts...

[jdkmunch]

does anyone know if there is a left and a right channel coming off the MPU-  that would explain it   --  cause the output from the MPU seems to be missing a "channel"

[jdkmunch]

OK - this has to be a corrupt EEprom -  I plugged the sound directly from the MPU out into a speaker and noticed that the sound seemed to break at a reel stop 

So I then turned off the reel stop sound  --  and you can clearly hear that it doesn't sound correct after each reel stop.    what chip are the sounds kept on?  I can report the checksum -

Check your plugs on the back of the LCD computer...
In post Reply#107 of the thread link below, there's a sheet I posted that may help...
This thread was fun to do and has a lot to do with your machine!...>>>

[jdkmunch]

Yes - Stout -  that two pin connector was plugged into the audio in port.    I've listened carefully totally bypassing the top lcd box and the problem still exists.    So my other post about skipping notes was wrong-  it just sounded like that to me.   


bottom line is output from the MPU is not correct

[stayouttadabunker]

I play my slot machine with my feet too...
Keeps the button deck clean actually when you use white socks!

[jdkmunch]

It's not easy standing on one foot, holding a baby in one hand, the camera in the other and playing with the other foot.   

[jdkmunch]

I need to know the checksum for SG085 and V8008GX0 to see if they are causing the sound issue...

any help would be welcome

[stayouttadabunker]

I usually sit down...
Then again, I'm not carrying little guys around either!

uh...the SGxxx GME1 & 2 chip pairs usually don't have anything to do with sound - the SBxxx chip does though.
The Version chips are for different jurisdictional denominations - again, not anything to do with sound.
I will look anyways...

[jdkmunch]

I'm going to have to read the sb chip - I can't view the number on the label. 

[stayouttadabunker]

IGT SB000008 DBL DIAMOND MINE 274002 0A48  -  where "0A48" should be the checksum for that SBxxx 3 reel chip.

[jdkmunch]

I have a SB000061 check 3EF2

[stayouttadabunker]

There IS another SBxxx on the list that matches yours.
I didn't know if it was for the 3 or 5 reel game though.
Unfortunately it shows a different checksum from yours...
This is what it looks like on my list ...>>>

IGT SB000061 DBL DIAMOND MINE * U21 27040 9UPA


But that does NOT mean your checksum is incorrect actually - it may be that this list just
shows a checksum arrived a different way...
I've noticed variances in checksums depending on what independent source
was reading their chips and how they wrote the values of their checksums.
Not everybody does it the same way I guess.

Also, I don't have this particular chip so that I could read it with a GQ-4X chip reader to see if I get the same results.
 
The machine plays... right?
So, I don't suspect anything wrong with your SB chip.
If the checksum was incorrect, you wouldn't even be able to get past the "boot up" mode.

[jdkmunch]

It does play correctly - except for the scrambled sound
