each version of the stage uses the same module st_bowsercastle_static.rel so if you are using a P+ based Build you don't
need to use the one provided

there are two versions of the stage, the regular version which is as you would expect it to be, and a Black and White
version based on the Refight in Ganons Tower. Besides the textures (and filesize since Black and White texutures take up
less space) the two are exactly the same, the Black and White version is meant to be a nice extra.
