Well, i have been searching for answers and i thought: why not asking to connoisseurs?
I had problems with this file. First, i converted this file from an online emulator, it was a .save. I searched a little and i too wanted to convert this file size, from 64kb to 128 kb. I saw the supporting save files for PKHeX, and i wonder, why is it going wrong?
