Game Input MultipleXer

Hi guys I have build a gimx for myself,but I have get some confusion and I have some question.
Questions 1: which firmware I should install to my gimx (pro micro) EMUPS4 or EMUG29PS4
Questions 2 :which config should I get in gimx launcher there are so many Logitech wheel .




Thanks for reply

1. EMUG29PS4
2. If theres no premade config for this wheel then you'll need to add it yourself. Look at the wiki for tutorial. It's easy.

First,I need to say thanks to GoDLIKE to give me a great answer.Now I can understand about the gimx launcher congfi.
