You have to post some file examples.

If you are using multiex, maybe this can help you: viewtopic.php?f=29&t=5921.

If you are using quickbms, please read Section 3 of this .txt: http://aluigi.altervista.org/papers/quickbms.txt.

Here it is: IDString "snail_package" ComType zlib Get U1 long 0 Get NFiles long 0 GoTo 61 0 For i = 0 < NFiles Get FNameSize Int 0 GetDString FName FNameSize 0 Get FUSize Long 0 GetDString Hash 32 0 Get FOffset Long 0 Get FSize Long 0 CLog FName FOffset FSize FUSize SavePos HOffset 0 Math HOffset +=...

I'm using MultiEx commander.

I've found a .bms script here: http://aluigi.org/papers/bms/others/blood_bowl_2.bms.

I think that this does it: #Blood Bowl 2 *.cpk ImpType Standard; GoTo 4 0; Get NFiles Long 0; GoTo 520 0; SavePos HOffset 0; For I = 1 To NFiles; SavePos FSizeOffset 0; Get FSize Long 0; SavePos FOffsetOffset 0; Get FOffset Long 0; Get FName String 0; Log FName FOffset FSize FOffsetOffset FSizeOffse...

I coded the script with multiex, not with quickbms. In fact, this error occurs but I don't know actually why.

I can try to code a quickbms script for you.

The first try can be done using this script: #Voyage Century China *.pcg files ImpType Standard; ComType ZLib1; IDString 0 "snail_package"; Get U1 Long 0; Get NFiles Long 0; GoTo 61 0; For I = 1 To NFiles; Get FNameSize Int 0; GetDString FName FNameSize 0; SavePos FUSizeOffset 0; Get FUSize Long 0; ...

You tried run files?

Yes, I tried to run the files and they are ok. I can listen to all the extracted sound files, I can send you if you want.

Of course you cannot repack back the files with this script, because it is not coded to repack back any files.

With the file sound.pcg I was able to get this: http://imgur.com/6jH1my4.

This seems to be the MEX script to extract the files: #Voyage Century China *.pcg files ComType ZLib1; IDString 0 "snail_package"; Get U1 Long 0; Get NFiles Long 0; GoTo 61 0; For I = 1 To NFiles; Get FNameSize Int 0; GetDString FName FNameSize 0; Get FUSize Long 0; GetDString Hash 32 0; Get FOffset...

Have you checked this post: viewtopic.php?f=35&t=12525?

You mentioned that the modified and original files must have the same size right?

So you want a extractor or also a repacker?

The files seem to be zlib compressed.

This is a sound extracted from 1 file: https://mega.nz/#!2QBiBYAD!_brRPzBweCyR ... fAazMavnms .

Can I do something to help with this?
