Basicly all you do is google "Fakemon or Fake Pokemon" and tons of results pop up. Tons of which are not used. Just drawn out. That and some say that you can use them as long as credit is given. I am going to make sure to give credit to the owners when the sprites are complete.
I think it would make more sense for you to send me the new files since I'm probably the most outdated lol, once again i cannot stress my level of sorry for all this.
