This is an amazing resource pack! I have a series on my channel that involves Pixelmon so it was amazing to find a pack that not only supports and adds textures to but also to vanilla minecraft. If you would like to see here is my review on the pack:
If you want a pack with the cries from the game you have to make it yourself and keep it private only for yourself. The sounds are copyrighted and cant be included.
Fair use says otherwise, so long as one doesn't claim ownership and/or try to make money off official sounds it'll be fine. And yes, that is the definition of fair use, as otherwise Mojang wouldn't allow mods to exist at all if that wasn't the case.
If Nintendo still claims copyright then, then they break the law by doing so since as much as I love them, they don't get the internet all that well.
Due to the appearance that this resource pack is no longer being worked on and that it is abandoned, this thread is now being locked. Should the author wish for this thread to be unlocked, the author can report this post and explain in the report they would like for the thread to be unlocked.
