Preston's Hex guide helped me out a bunch.

There's a link to a hex converter there as well.
Another thing that would help make pokes more legal looking would be a legal guide. Mostly for people just getting into pokesav but also as a reference in case someone forgets something.
General info as far as what's possible with things like "Ball caught with", "Met at level", "Met in Place", "Date Met", "Egg hatched at", "Date egg received", "Region" (I forget to put that one A LOT).
I guess it would be possible to throw together a slot by slot reference for newbies but it would be time consuming and I'm pretty sure I've already seen one or something like it floating around. I don't want to reinvent the wheel, so to speak, so if there isn't one I could do one but I'd probably just reference Preston's Hex guide in the hex section as it covers everything well.
PS - I know I have a low post count, but it's because I'm mostly a lurker. Hahaha.
