I've been looking for some files within Pokepark 2, in particular Piplup's (would be indexed as Pochama) brres file but whenever I search for it through Dolphin's filesystem feature they seem to be missing that one and some others from what I noticed. I've noticed this for a few other games too and am curious, what would be other ways I could find the files otherwise and also how come those ones are missing from Dolphin's filesystem while others are present?
