When I tried to extract the data.xp3, cmd showed something like this:
C:\Users\Innnova>cd c:\xp3tools-20060708
c:\xp3tools-20060708>xp3-extract.exe E:\Games\Japanese\愛母乳辱~妄執の巨乳責めザンマイ\data.xp3 E:\Games\Translation files
Expected "#01" at position 0x32837 but saw "#00".
Traceback (most recent call last):
File "xp3-extract.py", line 104, in ?
assert (indexoffset+compsize+17 == filesize)
