Is anyone know, Is it possible to extract music tracks from "Grand Prix Unlimited" game? Some filenames mentioned in gpu.exe file:

GPU1.MUS
FSGPU2.MUS
FGPU3.MUS

But I can't find where this files actually located, possible inside GPU.DAT?

EDIT: Split from Extract MIDI from Accolade DAT files? as it was a really old necro.
