This is my first time doing one of these kind of threads. Dragon Ball Heroes RomFS is made up of 1 file (DOF.cpk). The file format is used in Xenoverse and can be easily extracted/repacked with QuickBMS. When extracted, the file consists of files like jtex, jarc, jmdl, usm, etc. I haven't found the files for the text (unlike Ultimate Mission 2, which is in .Mes files). @nobody231 and I are working on hacking the game in my Ultimate Mission 2 translation thread but I decided to move it.
