Hi, I am also very new to all of this. I went through these steps: compiling PKHeX and making a folder called "plugins" to put the WC3 2.2.2 into.
I had an issue when running "Build" initially, but I fixed it (I think) based off previous responses in this thread. I rebuilt it and it did it successfully. I opened my save of emerald through PKHeX as well.
However, I am now getting this issue when I try to access the Mystery Gift or Mystery Event option in the plugin:
I'm a bit confused. I get that it's saying that the file isn't there, but I was wondering if someone could provide some advice as to what I should do. Let me know if I need to provide more screenshots or anything.
Thank you!
