For the
HG/SS Items update, there are a couple of things that need checking before I have all the info needed. First, How Heavy Ball affects the Catch formula. Smogon's GS page implies that the boost against heavy Pokemon is a simple multiplication, which is contrary to everything else I have found.
Serebii suggests the following:
If the Pokémon is Less than 220lbs then -20, Between 220lbs & 440lbs then +0, Between 440lbs & 660lbs then +20, Higher than 660lbs + 30 -20, +0,
+20, +30
While
Bulbapedia suggests:
Between 100kg* and 200kg*: +0
Between 200kg* and 300kg*: +20
More than 300kg*: +30
Under 100kg*: -30
The weights are the same (just different units), but for under 100kg they disagree on how much is taken from the catch rate.
Next, what on earth is the Rock Capsule? A few places mention it, and I've seen the sprite, but other than a load of uneducated guesses and random conflicting theories.. almost nothing. Even Bulbapedia does not have a page for it. Seems likely its a wi-fi event item of some kind, but that does not help much. I could put up a description of "Unknown", but surely someone here can find a bit more info than that. Hex is 0x0215 according to bulbapedia's item list, and only in HGSS.
And a minor point, if someone could hack a Rule Book (hex: 0x01AE) in DPP and see exactly what it does/says it would be nice.
