This is kind of a weird case, so I'm not sure if this is the correct subforum for it. Apologies if not.

I've extracted the Unreal .pak from the new PC port of Triangle Strategy and I'm interested in the BGM.

I've found the music streams in "TRIANGLE_STRATEGY/Content/Newera/Sound/Stream/BGM.awb", in CRI AWB format, but without a corresponding ACB file, the tracks don't have labels/filenames.

In "TRIANGLE_STRATEGY/Content/Newera/Sound/BGM", there's "BGM.uasset" and "BGM.uexp". Their filesize is small enough that they can't contain audio, but looking at the .uexp file in a hex editor, I can see what look like BGM labels, e.g. "BGM_M43_ADV_BEAUTIFUL".

I assume this is some kind of index which should be able to identify the tracks in the AWB file with these labels, but I'm not sure how to use these files to get the association between the labels and the tracks. It doesn't seem to just be in the same order between the two files (e.g. BGM#1 in the AWB doesn't sound like it should be "ADV_BEAUTIFUL", the first string in the .uexp).

Does anyone have ideas for how I could do this?

The AWB file is too large to upload, but I've attached the .uexp and .uasset files in a zip.

How did you extract the pak file? I can't get quickBMS to do it even after finding the AES key.

Oh, I had trouble with the stock unreal_tournament_4 script as well, I had to use "unreal_tournament_4_0.4.27d_paks_only.bms" from this post. Sorry, I should have specified that in the OP but I mixed up what's in my notes and what I posted.

I'd like to subscribe to this, umodel can't extract the files either.

What is the AES key? Is it: 0x75D4C74524DE13DD968F3DE80349A6C984912E76A67E6851280EF1F01BFE4946 ?
