If the mon is from Gen 2, don't transfer it to HOME.
If the mon is from Gen 3, you can transfer it to HOME. PKHeX flags the PID and stuff cause the event isn't well documented, in regards to the generation algorithm and all, but since you know it's from the machine, it's good enough to be used. HOME doesn't care for the most part.
