Used in the following game(s):
- Yuno
Index appears to be protected. First 4 bytes are number of entries in index/number of files in archive. Even with this, a quick look and guess work shows an index entry is 28-bytes in size. Filename space is 20-bytes, followed by (probably) two 4-byte numbers. Appears everything but the initial 4-bytes that stores the file count is protected. As for the protection... Appears each byte is XOR by 0x03 for at least the file names.
0303030303030303030303
=
0000000000000000000000
thus
5A564D4C5C32322D544255 (ZVML\22-TBU)
=
59554E4F5F31312E574156 (YUNO_11.WAV)
...really? ^^; Didn't even need a debugger for that. XD
And now for the data after that...
(Future me: ...did I really type that?)
