I use MaxConvert for converting codes though I use it for Action Replay 2 v2 codes but it converts to Max format aswell and a few other formats
Anyway I attached a copy seen as I don't know the home page for it or remember what site I got it from
There is one site that has some information that may be handy but it's more for the AR2v2 but it should help you understand the whole (M) code thing and how it effects all your other codes when converting them
one site
Edit :- visit
here for the newest version
just found that now..
Edit again
beter linkage <- bookmarks that one myself
I'll be trying out some new hacking methods sometime me thinks
