Hi all,

Looking for help with this files. They extract OK but some of the filenames are cripled, can you please help ? Strange thing is that in HEX it looks the same




Using this script..

Code:

endian big
idstring "BND307D7R6"
goto 0x10
get files long
get start long
goto 0x20
savepos tbl
log MEMORY_FILE 0 0
for i = 0 goto tbl
get unk01 long
get zsize long
get offset long
get unk02 long
get nameoff long
get size long
savepos tbl
math nameoff   3
goto nameoff
get name string
if zsize == size
log name offset zsize
else
clog name offset zsize size
endif
putct name string -1 MEMORY_FILE
put 0x0a0d short MEMORY_FILE
next i
get size asize MEMORY_FILE
log "names.txt" 0 size MEMORY_FILE

Samples :

Do you know if quickbms has dumped the filenames correctly?
I guess that some chars are corrupted due to the cleaning of the filenames (probably I will add an option to disable it).

To be hones it is same if i hex it. SO i guess merlin is right, but exprot you can see on screen it is not correct or my Wind cannot display JP chars

They are dumped exactly like in files are, but saved in ASCII and not in SHIFT-JIS (or UTF? don't know). But manually I can rename that files to have japanese characters in name, so I don't know if it's matter of QBMS or operating system.

*edit*
I thought that ",ccs=UTF-8" in fopen was for the filename, instead it's for the content so it's useless.

I don't know why the filenames are saved as ASCII, probably a limitation of fopen.

Did you used WideCharToMultiByte with that codepage to convert the utf8 string to utf16 for CreateFileW?

It is written in .NEt so i use this :

Code:

Encoding.GetEncoding(pageCode).GetString(this.ReadBytes(Length, Endian.Little));

BTW : i found the very powerfull way to handle binaries in .NET really super easy method at least for extraction for now
