I don't believe so. I downloaded the .tbz2 file from the above link, extracted using archive utility, and then attempted to open the PKHeX application afterwards. Multiple attempts at downloading have not been successful either.
yup I was originally!
Pretty sure I was using an older version, so I got rid of it & tried downloading the newest one from projectpokemon. Then this popped up.
I'm attempting to use pkhex by using the sound hack method. I believe I've set everything up correctly, but when i try to put my file in the pkhex application it says "attempted to load an unsupported file type/size. Any idea how to solve this?
