Might be 2 years too late on this, but recently I acquired a Razer Panthera and have been enjoying my time with it. Currently it's disassembled as I'm expecting to get a custom panel soon, but I digress.
I acquired a brook UFB gen 5x for very cheap and I wanted to install it into the Panthera. I checked the websites arcadeshock and jasen's customs for the EZ mod as I still wanted to use the on-board functions like the touch pad since its placement is very handy for practice mode resets with one hand in Tekken. But alas, it seems the EZ mod has been discontinued.
That being said, is there ANY alternative to what the EZ mod did for the OG Panthera? Or am I just too late in getting this PCB mod? Hell I'd be willing to buy it off someone secondhand because I love the Panthera that much.
