Final Fantasy Dissidia NT uses 2 container formats for all of it's audio, BGMs use a g1l wrapper, which actually does nothing, delete the first few bytes of the wrapper and it turns out BGMs are just standard at9 files for Sony consoles.
Voices and Sound Effects on the other hand, seem to be on a .sed container, with the bms script made for another game (Fatal Frame: Maiden of Black Water) found here ( http://aluigi.altervista.org/bms/fatal_frame.bms
) and changing the endianess from Big to Little made it successfully unpack everything inside the .sed, in most cases it spits out 2 files, one "small" file with a header of _HBW0000, which I assume to be WBH_0000 due to endianess, and a "big" one with a header of _DBW0000, or WBD_0000.
They both seem to be linked somehow, WBH seems to contain file IDs? While the WBD file would be a sound bank of sorts, maybe with headerless streams?
Here are some sample .sed archives from the game, If anyone could help figure this out I would really appreciate it.https://cdn.discordapp.com/attachments/ ... oice_e.sedhttps://cdn.discordapp.com/attachments/ ... tvoice.sedhttps://cdn.discordapp.com/attachments/ ... oice_e.sed
