Try something like this:

I've managed to get somewhere with this. I was looking at the rom history on another website and it seems the dip switch function is broken in the driver. The workaround is to make the changes in service mode. I have tried this and can verify that it works. Changing them from the mame menu would be better, but as its usually only a one-off change, I'll live with it.

@HPTF2020 - ISSUE RESOLVED - I had the games in the LR-FBA ROMS Folder which did not allow the dip switch setting menu to open when pressing F2 or TAB, however, when I moved the games to the Mame4All Rom Folder that functionality worked
