IGS PGM Button mapping

[nassekova]

I have my IGS PGM working fine, but for some reason coin button does not work on it. When I was playing with HAS and external joystick, it was not that big of a deal, but now when I have the Blast City I would like to get the coin mech to work with it. Right now "service" button adds coin and "test" button does nothing. I googled about the pinout and it should be starntard JAMMA with coin in slot 16? Is there a way to set it at least on free play?

Game I am playing is conversion Espgaluda.

Dip 4 is free play normally, but I would be surprised if it worked with Cave conversions. Normally for Cave games you have to press and hold the test button to enter the test menu. There you can switch the game to free play (if there is one).

As for coin input, should be the same as any other jamma game?

If you boot it without a cartridge you'll get a test menu, including an "i/o test". This shows all buttons recognised by the system.
If they work in there it is a matter of how the game interprets the button.

Test button worked after I hold it, so that now works and I can get it to free play. Coin issue seems to be my coin mech on Blast so this was not IGS PGM related after all.
