Unable to configure ipac ultimate

[EspenT]

This is my first arcade cabinet build and i decided to use a Retropie image[Removed]. I have a ipac ultimate and i started out with the default ipac mapping and the Retropie "configure input" tool to map Player1. I manually edited the all/retroarch.cfg for player2. Player1 worked as expected but player2 would change playback speed etc..

I then followed this guide.
https://retropie.org.uk/forum/topic/8987/guide-setting-up-a-retropie-controls-using-ipac2-controller-extensive-tutorial-preconfigured-files

In the Menu controls will work, but after launching a game i still ned to push "5" on the keyboard to add credit. When i insert a coin a "y" is correctly registered but does not trigger anything.
Pressing "Start" will register as a "h" which is somehow mapped to "reset" and the rom vil reload.
Pushing "tab" will open the emulator menu but no buttons are mapped to exit there.

Somewhere there is some button mappings I can't find and don't understand. But where?

I tried to config the buttons through the main input config area while retropie was running and found that retropie recognizes the Ultimate OI board by Ultimarc as one game controller. Seems to me it has to be configured through the script manually. I'm trying it tonight to see if I'm successful. Did you ever get yours working @EspenT ?

Thanks.
