I looked the place with map editor and saw there really should be trainers there although I didn't believe it at first.
I made my own walkthrough for this hack months ago so I don't remember what to do but go check it out in youtube.
Yeah i happened to look at the video where this is happening, and there is regular trainers there to fight but on mine there is none. i'm thinking that i missed something but i don't think so since i followed the walkthrough thoroughly. Oh well thanks for you time i will try to find something out.
