Not surprised. Thought I'd ask before attempting it myself, so as not to re-invent the wheel.
I have other options including an AIM-Trak installed in a hap recoil shell, but I like the look of these guns better (Walther P99 replica) and having it wireless would be cool. I may end up sticking the AIM-Trak in one of these shells, but it has a d-pad and bunch of buttons that will go unused.
....or maybe just leave the gun games to my old CRT setup since I really don't like IR guns anyway.
