Williams Roller Games sound problems

[Per Jensen]

Hi.

I've recently bought a Roller Games pin.

It's originally from Germany (i'm from Denmark) and the machine spoke
German. The original eproms was Rev 3.

I burned some new eproms with a L2 version of the firmware (American
language) and put them in. it works perfectly, there has just come up
this little detail that bugs me.

When the title song starts playing and the singing begins, it loops
ontop of itself - it does not sing the whole lyrics before cutting in,
and starting over again. It sounds stupid.

It does this both in-game and in the test menu. It's the main title
melody (01)

I've tried swapping in the old eproms again to see if there is some
difference, and there isn't.

I'm pretty sure that this machine wasn't like this when i got it.

What can cause this ? Bad eproms on the sound board, or maybe even bad
caps ?

I'm going to do a recap job on the power supply board soon, just need to
collect all the different caps.

As i am amidst of moving to a new location, my eprom programmer is
packed away, so i can't easily check the checksum of the three sound
eproms right now.

Has any of you seen (heard :-) this problem before ?

If what i'm writing, is complete rubbish, i could record a small audio
clip of it for you.

Regards,

// Per.

That might be your best bet, as I'm not *really* sure what you mean. (If a
picture is worth a thousand words, a sound file is easily worth five
hundred! :) )

If it has the German sound ROMS installed, they sound a little different
than the American ones. Might program a set of them and swap them in.

The way you describe it reminds me of the German sound ROMS.

I was thinking the same thing, which is why I want to hear what he's
hearing.

Sounds like the German Sound Roms. I ordered them and have to say
that I actually prefer them to the original song - doesn't get stuck
in my head as much. To each his own!

Well i shot a video of it.

Does anything sound out of the ordinary ? Maybe it's just me that
remembered the song as being different.

remove the ribbon connector, check the headers (small pins). If ok,
change the ribbon connector. im willing to be its that.

You're right -- that does sound really retarded! (i.e. yes you have a
problem! :) )

My guess would be that the ram on the sound board is flaky / bad. The
sound board is losing its place in the song. I don't think it's the roms
because you'd have a rom checksum error. So that leaves pretty much the
RAM and the CPU chip as possible culprits in my mind.

Do you have another similar sound board hanging around? I'd swap RAM &
CPU chips around, see if the problem disappears.
