Yes, do what you like with them. I have the source as well if that would help anyone improve them. I just figured it was easier to put the executable out there. Some of the trainers took several hours to several days to figure out and make. But I was just doing it for fun. When that wears off, I will probably stop making the trainers.
I had also thought about renaming them to 8 character names instead of the 6 currently used.
