you can get the files without names like this.
just use offzip
offzip.exe -a -z -15 C:\Downloads\agdata1.pak "C:\Downloads\New folder" 0x0

its a modified zip format with the central directory compressed too - but that's extracted by offzip at the last block (see 00c8f11c.dat)
i noticed 26 spare bytes from the last file to the file size, which looks like the eocd and perhaps a pointer to the compressed central directory, but i failed to get anywhere else. (i just saw 05 06 as part of the eocd signature)
anyway. we can botch extracting these files with filenames
1) in a hex editor, copy the contents of 00c8f11c.dat at the start of agdata1.pak and run this bms:
Code: Select all
# - WRS
# workaround bms
comtype deflate
for i = 0
idstring "PK\x01\x02"
savepos SKIP
math SKIP += 16
goto SKIP
get ZSIZE long
get SIZE long
get NLEN short
get ELEN short
get CLEN short
savepos SKIP
math SKIP += 8
goto SKIP
get OFFSET long
math OFFSET += 56516 ## size of our temp header
getdstring NAME NLEN
savepos SKIP
math SKIP += ELEN
math SKIP += CLEN
goto SKIP
if SIZE > 0
if ZSIZE == SIZE
log NAME OFFSET SIZE
else
clog NAME OFFSET ZSIZE SIZE
endif
endif
next i
