BVP

BVP is an Atlus format that contains BMD messages. Unlike BF, this format is only used for Navigator Character text, which appears in an overlay on-screen during active gameplay, like in battle or dungeon crawling. Currently, it's possible to convert BVP to an editable format and back.

Usage is easy, just drag the file you want to convert into the EXE and it'll generate the new one. You can get it here.
