Comes with this: https://www.mpgh.net/forum/showthread.php?t=1382644 . You just need to learn to use the trainer 1st.
DF Generator is just a name, it basically do the same things as some SWFs. Just like LolSalad's Gold&Exp Generator application did. They all use (I think) some specific quest ID, load and finish quest. So I think you better download the trainer now, instead.
or use SWF (https://www.mpgh.net/forum/showthread.php?t=1231304) instead, but trainer should do the same thing without any external cheats.
