I think that you should be posing these remote questions on a forum dedicated to those remotes. Stick to whether or not they work with GameEx here. To answer that question: they should. So long as their input is mappable in one way or another, things should work just fine.

What happens when you press the middle mouse button normally in Windows?

Sometimes, people won't do something unless they're assured as to how easy it is.

Yeah. You're using the wrong build of Gens. I was using the wrong build of ZSNES and it kept failing on me, over and over. I downloaded the latest version from zsnes.com and that fixed my problem. (GameEx automatically downloaded the older version...) So, if you haven't already, switch. You won't get a nosebleed, I promise. FWIW it's really easy to use Fusion. It took me literally 2 minutes to get it to work with GameEx. If you INSIST on keeping the same emulator, I recommend making sure your settings in Gens ensure that the emulator loads in fullscreen mode.
