The brres files (used in multiple Wii games like Super Smash Bros. Brawl) in this game appears to use huffman compression.

Here is a sample zip file containing a brres file under the filename of ch01a_gintoki.bcmdl that was extracted with multiple quickbms scripts.

Turns out I found out that lzsd_of.exe can decompress most compressed brres (the ones that end with z) files extracted from .pac files from that game. 🥰

Oh, I just forgot, there are some files that cannot be currently be decompressed yet or can be used by lzsd_gba2.exe or lzsd_gfd.exe but here's a zip containing files from o_title.pac.
