There's nothing to follow.... unless you want to deal with the objectively crappier guns designed to work with an lcd, your options are to find an pc-based gun on ebay and use it... that's about it. The guncon stuff is a bit of a cludgy hack imho. Once/if you get it to work then it is a good solution, but if you want something that "just works" you are better off getting an old act-labs gun.
