Ok, I saw a video on building an emulation station using an ultimark ipac2 with the raspberry pie. I have used a ipac before using mame on a PC. This video seemed to show the ipac being plug and play, but it sure isn’t. I have done numerous searches here and google and have watched numerous videos, but none seem to cover the ipac2. I have went through the pi and updated everything and ran all the set ups, but when I configure the controller in retro arch, nothing works. Half of the buttons don’t even register. Now I assume I can edit a config file, but that is beyond my level without some help.
Can anyone please put me in the right direction? I am desperate.
