Are you saying the 10 pin connector is a 1:1 match to the DIP Switches? Like, I could use jumpers to select games instead of the DIPs or is that connector's functionality a little different?Those are basically only "data"-lines. You can compare the function with the dip switches next to that connector.
Game changing via dip-switches (without selector at all) works fine?
When you're trying to use the selector, are all dips set to 0-position?
Ok, I have no experience from the Multi-Pi -selector.
Game changing works fine using Dip switches without selector.
Yes, all dips are set to 0/Off when the selector is installed.
