Yabber

An unpacker/repacker for common Demon's Souls, Dark Souls 1-3, Bloodborne, and Sekiro file formats. Supports .bnd, .bhd/.bdt, .dcx, .fltparam, .fmg, .gparam, .luagnl, .luainfo, and .tpf.
In order to decompress Sekiro files you must copy oo2core_6_win64.dll from Sekiro into Yabber's lib folder.
Does not support dvdbnds (the very large bhd/bdt pairs in the main game directory); use UDSFM or UXM to unpack those first.
Also does not support encrypted files (enc_regulation.bnd.dcx in DS2, Data0.bdt in DS3); you can edit these with Yapped or unpack them with BinderTool.
Requires .NET 4.7.2 - Windows 10 users should already have this.
