Dirt 4's nefs files

[phoenix]

Hi, the just released Dirt 4 from Codemasters uses nefs files.
I tried using codemasters_nefs.bms with no success.
error : can't read 1 bytes from offset a74527a9

Appreciate it if you can take a look.

Attached the file tested (first partial file as can't upload the whole file)

I guess that currently it's better to use offzip do to the job:

Code: Select all

offzip -a -z -15 -Q -x -c 0x10000 str1.nefs OUTPUT_FOLDER

When I will have time and desire I will update the script

Hi Aluigi. I have the same problem...

[phoenix]

Hi, what should be the command for injecting the modded file back using packzip ?
Thank you.

[aluigi]

offzip has a -r option that works just like quickbms but honestly I don't know if it will work in this particular situation with chunked content.
If you want to try it's just the SAME command-line you used for extraction plus the -r option just after "offzip.exe", remember to make a backup of your archive.
Obviously there is no support about this, it works or doesn't work.

Thanks. Tried and didn't work.
Error :the compressed file is bigger than the original by...

may I ask if it is fixed too?

same problem here.

waiting for the reply

[aluigi]

No way to fix it.

[zissakos]

what exactly does it mean "no way"?
Technically impossible? encrypted?

I managed to decode the nefs file and get the single files. So there must be a way to get them back into a NEFs file right?

hi,thanks aluigi
no any way to import big .nefs file?

[aluigi]

Eh no, for 2 reasons: first it's usually necessary to dump the archive in a temporary file and then it uses chunked files.
I don't know if splitting the script in two parts and using the chunks without the MEMORY_FILE may change something but usually there are ever problems (even if quickbms has been tested to work with chunked files [memory_files too] in reimport mode but people report ever problems)... in short the main rule remains the same: if the game uses chunks you can't reimport the files.

Thanks, all files are extracted
But there is only one thing and there is a problem that was in the previous script.

Choose R

Choose R

I knew this
I just wanted to tell you
Thank you

[aluigi]

Ah ok.
Yeah it happens also with other Codemasters games, probably they are duplicated files.
