Was there any official reason as to why apricorn balls/apricorns can't be given as held items? Is it just to prevent them from being traded backwards to D/P/Pt?
I assume, there probably isn't code for Apricorn Balls in the Sinnoh games.
On that note, can you trade pokemon in Apricorn balls from HGSS to DPPt? I assume if you can, they'd be in standard Pokeballs.
