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? 🙏
