alpha testing stuff left in the rom

Ahh, I see. My thoughts were that B/W were based off DP

[Kaphotics]

From what I heard, the development for HGSS was concurrent for when B/W was, they were both in development at some point in time. Thus B/W could not use the edited engine HGSS did (or all of the features that were added).

you can see pokemon sprite, is based on DP...........

There are lots of scraps from old games leftover. HGSS has underground data from DP as well. It follows this sort of flow, where scraps from a game before show up in the more recent game.

DP -> Pt -> HGSS
       `-> BW
