I checked it all. The entire body is semi-transparent, as it should be, with the only marshmallows being the stars where they're actually supposed to be.
As for black and yellow areas, there are none. Even in the test, I scrolled to check the underfur, and found nothing. There are no equip files, I don't think, but the mane files worked just fine when tested, only with a slightly darker color.
And I also kinda figured that it would have been 'Inoheiwa_1.fhp' in the files, but as mentioned, there were no files of the sort.
