Problems at configuring P3 and P4 controls

Hi. I've made an arcade machine with Retrobat but I'm facing some issues when connecting 2 more sticks to play with firends.

The main problem is these 2 additional sticks get configured automatically as P1 and P2 controllers, which means the arcade cabinet buttons can't operate properly. How could I set them as P3 and P4 instead? I've tried in Retroarch configuration but changes are removed once I open Retrobat again.

Something similar happens with remapping cabinet controllers. I set each button at input menu (both Retroarch and Retrobat) but these configs restore to default by themselves.

Thanks a lot for your help.

Hello
You maybe should be more precise on the material you use, before real professionals came to help you.

I'm using arcade stick and buttons like these in the picture. I think the problem with mapping has to do with board conections, so that shouldn't be a big deal.

The problem is I can't set them as P1 and P2 controllers. Always additional controllers get set in first and second place

Hi. Just to provide some more info, I add an image showing the messages at launching any game. As you can see, both G-shark sticks are configured as port 3 and port 4.

How could I change orders to set them as 1 and 2?
