Kirby Triple Deluxe BCH.CMP files?

[Curby]

Im trying this and nothing seems to be working. maybe I just downloaded it wrong or its damaged or in the wrong format, but when I try opening the bch.cmp files in ohana rebirth, it just gives me a warning. im new to this and don't really know what im doing. im just trying to get the Kirby models from triple deluxe and robobot so I can make a low poly video of my own.
