first off, rapid fire dosnt really work in halo, it does, but it dont, single fire wepons yea its good, but how many are there???? 1 maybe 2?? the rapid fire for halo dramatically increases accuracy though. this is all due to in game programing, which there is no way around.
as for the wireless/wired deal, I told you at the start, I dont know of anyone who can answer this, most of the guys here only deal with wireless, I have 11 controllers now, all wireless. you can wait for someone to speak up that has done it, or you can try your self and let the comunity know if it works or not.
