Summary 06261: polepos2: Crowd Cheering sounds are messed up at the chequered flag (goal).
Description I have verified an anomaly between my original Namco Japanese PCB to the Mame version.On the original PCB,on the final lap,at the chequered flag On Mame, the crowd cheering sounds are partially missing and original rom set also hides the male announcer speech,and plays the crowd noise only!
Steps To Reproduce I have placed the 4 sound epproms in the correct order on the pcb.PP1 11,PP1 12,PP1 13,PP1 14 according to the mame layout and have used PCB pics for reference.The male announcer voice disappears,leaving just crowd noise.It must be hidden on one of the epproms.If you swap PP1 12 and PP1 13 around,The male voice reappears.Very unusual.
Additional Information This only affects the Namco boards.The Atari boards only contain PP1 11. The other eeproms have been removed.(no crowd or male voice.)
I'm not sure if this affects the original Pole Position Japanese version,as I don't own this PCB,but it is most likely the same issue. (poleposj)

The honor of a video or audio recording of the situation would do wonders here.

I meant to say.. an original recording from your Japanese PCB for comparison so the developers know how it is supposed to sound. Video of it would be a plus as well.
