Is I bad for your computer or anything because I was thinking about using it since I really hate EV training & all the hard work.
If there is any reason it could be bad, please tell me & I won't use it.
Pokegen is a hacking device and as such has potential to harm your game though it is not very likely. Many people look down upon this sort of thing but as long as you keep it to removing tedious jobs: EV training, Breeding, Natures etc. Most people on this site at least won't annoy you about it.
