Unpack music from VVVVVV's music file!

That one should work even with added files.

noice!

I made a Java clone of this. Should work with Java 1.8+

Works with added files

https://gist.github.com/BenjaminUrquhart/53c5abf9599e457a291510e007e5b957

python3, works with arbitrary files:

import struct
import os

with open('vvvvvvmusic.vvv', 'rb') as f:
    data = f.read()

# find filenames

# (name, len)
headers = []
iptr = 0
while data[iptr] == 0x64:
    headers.append(list(struct.unpack("<48s4xI4x", data[iptr:iptr+0x3C])))
    headers[-1][0] = headers[-1][0][:headers[-1][0].index(b'\x00')]
    iptr += 0x3C

moffset = 0x1e00

if not os.path.exists("data/music"):
    os.makedirs("data/music")

for n, length in headers:
    with open(n.decode('ascii'), 'wb') as f:
        f.write(data[moffset:moffset+length])
        moffset += length

seeing someone from years ago solving your problem you didnt even know you had until 5 minutes ago is always the best feeling.

thanks guys

This still works as of V2.3.

Had to fix some things, and posting so people don't have to go through this again.
