How to extract the .obb file of the game Field. Thanks!

This is the file: http://www85.zippyshare.com/v/gWTzCeRY/file.html

They are just zip files.

They are just zip files.

But when extracting it, you see the files like in the image:

[Hocmai]

I do not know how to view and edit it. Hope you help me!. Thank you so much!

The files in the obb you uploaded are xored with 0xf8:

Code: Select all

filexor 0xf8
get SIZE asize
get NAME filename
string NAME + .
log NAME 0 SIZE

I can't know if the same obfuscation is used in the files of the other obb too.

*edit* fixed

I get this error:
Error: invalid datatype filaneme at line 3
Last script line before the error or that produced the error: 3 get NAME filaneme

[Acewell]

typo, line 3 should be

Code: Select all

get NAME filename

[Hocmai]

typo, line 3 should be

Code: Select all

get NAME filename

Thank you! Acewell. But I just get the .dat file. It does not extract the parts inside the .obb file that I need. Can you help me!

Because you are using it incorrectly, I already told you that obb is just a zip.
Extract obb as a zip and THEN use the script on all the extracted files.

Thank you! Aluigi. I extracted it in a nice way, I actually used it incorrectly . Your script is very effective! Thank you again!

*edit* wrong, ignore.

Just for information, there is also a second way to the job.
Download http://aluigi.org/bms/zip.bms
Open it with a text editor and put the following line just at the beginning (first line):
encryption xor "\xf8"
Use the modified zip.bms with quickbms on the obb file, all the extracted files will be already decrypted.

Thank you! It will give me more options.

Unluckily! I get this error from cmd when extracting this game file:
Error: the compressed zlib/deflate input is wrong or incomplete (-3)
Info: algorithm 2
offset 00000026
input size 0x0000047a 1146
output size 0x00001443 5187
result 0xffffffff -1

Error: the uncompressed data (-1) is bigger than the allocated buffer (5187)

Last script line before the error or that produced the error: 220 CLog name offset comp_size uncomp_size

This is the file: http://www116.zippyshare.com/v/GxUU6tJh/file.html

[aluigi]

Right, my fault.
The encryption of the game is post-extraction, not before extraction (as used in zip.bms), so that solution can't work.
Forget it, use the normal method

[Hocmai]

Aluigi! I see how your 1st one will need improvement. By! If you do so, you can only extract one file at a time. It will take more time, instead you can do it extracted all at once but only once. Thank you!

[aluigi]

Remember that with quickbms you can select a whole folder as input so you can use the first script on all the extracted files in one operation.

Thank you! I really did not realize it

[Hocmai]

But there was an error, when I selected all the files. The quickbms window is closed
