Also, can anyone confirm that the move and item data structures are the same for R/S/E, D/P/P and B/W? I managed to find move and item specs for the third generation on Bulbapedia, but not D/P/P or B/W. I can't imagine items and moves would need new attributes for the fourth and fifth generation games (new enumerations can be made for the move's target and which bag the item is placed it), but that might not be the case. This isn't as important as the Pokémon and species data, but it'd still be nice.
I can tell you the item structure is the same because the same dummied items exist in B/W.
Anyways, that tutorial you pointed to me didn't have 100% wat I was looking for, but it did somewhat confirm something. THe game uses some kind of sample. But, I need to know
A. Where they are
B. What instrument they are assigned to
C. What format they can be extracted in.
