Im not a hundred percent sure, it may, it was made so that you could use codes together that use the same subroutine, because if two codes use the same subroutine, it will freeze you. apparently you are supposed to edit your selective kills to include another line, but the one that I use is probably the same one as everyone else, and I just turn on multihooker first, then turn on selective kill, and it will let me turn it off, where i used to freeze everytime i tried to turn it off. for more info search this forum for multi hooker, cus after i wrote that post, i searched it, and omega released it on this site, and he explained exactly what it does.
