There is already more than enough info in the forums now on R/F controllers, people just aren't bothering to look it up or ask in the appropriate threads where that talk is taking place.
From now on if any new threads are started that aren't some kind of already completed (and at least decent) tutorial, or something new on the subject, then they'll just be Closed.
The main threads going on now, with probably all the info you'll ever need to make a R/F controller, and if it's not, in one of them is where the people that will have the answers for ya are, those are located here..

The 'Two-Wire' or 'No Chip' Rapid Fire mod works ONLY on the older version Matrix controllers, it does not work on the newer CL or CG versions and isn't preferred by most anyway as ya have no ability to change the speed of it. If ya need to know more about that method there are tons of tutorials and videos on the web, just Google 'two wire rapid fire' or 'no chip rapid fire' and there will be more than enough of them to look thru.
If ya need to know what version of 360 controller ya have look in the Tutorials section, the first party M$ brand ones are in there.

Please read thru them for any answers ya might have, yes I know they are pages and pages long, it's probably already been answered more than a few times and if not in those threads are the best place to get your answer since the people doing those controllers are posting in there.
This will be updated as well and if anyone has something that they think should be posted in here as well, additional tutorials or such, then PM me about it and I'll edit this accordingly.
