It's probably PGM polygame master board games. Espgaluda and knights of valor are other examples.

I still don't get why this is a thing. I know espgaluda and ketsui both ran in Japanese arcades with the same coin drop and cab that I have. Maybe it's a mistake with the mame driver for PGM.

Anyway glad to have a fix.

There does appear to be a bug in the coin_impulse code, In that the doc say if value is smaller than 0 then disable the impulse.
(n<0 disable impulse, n==0 obey driver, 0<n set time n).

However when setting the value to -1 or smaller, The coin_impulse still fires (As if the value was 0 == obey driver which usually means for as long as the key is held down).

<Added>
On second thought,
It may be that some drivers force a "coin_impulse n" - And the disabling option might be for those specific cases.
But generally (most drivers?) would simply make the pulse the length of the key press when obeying the driver.

I see you all solved this problem three years ago, but I think I may be misunderstanding the solution. I have a Groovy MAME cab and it’s not recognising coin insertions for the three CAVE PGM titles (ESPGaluda, Ketsui and DDP DOJ). I’ve seen that I can fix this by changing the coin_impulse setting, so I created a pgm.ini file with coin_impulse set to 8 and dropped it into the MAME/ini folder, as per Ozfalcon’s advice. Unfortunately it’s still not reading coin drops, leading me to believe I’ve formatted the ini file wrongly.

I’ve tried the following:

“coin_impulse 8         1”

and

“coin_impulse            8”

Can anybody tell me exactly how to format this ini file? 🙏
