Xenoblade Chronicles 2 - Modes Rips (Golden Country Stuff Added)

[Sir Teatei Moonlight]

(might as well post here too to widen visibility) here's another one I need help with that I hear is also in XC2: .wiefb files, which hold the models and textures for things like model attachments
an example from XC1DE:

Code:

78 62 63 31 01 00 00 00 00 40 39 00 61 9b 10 00
dd 68 a4 d4 65 70 30 34 34 31 2e 77 69 65 66 62
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
78 9c ec bd 0d 78 55 d5 95 30 bc ef ff ff cd 4d
72 43 12 08 10 48 80 00 01 42 12 20 62 20 07 08
