ROM Hack Need Help with hex editing pokemon yellow save

[Alan Drumm]

So I've been trying to hex edit Pokemon yellow saves that I extracted with JKSM. But every time I import the save back in Pokemon yellow it say that the save was corrupted or damaged, now if I edit the same thing in pikasave it works fine. Is there some check that is making it think its corrupted?
