REIMPORT MEMORY_FILE WORK-AROUND ???

[cornel]

"Do you want to use the experimental reimporting of chunked MEMORY_FILE?"

I get this option when trying to reimport modified wav files (with the same size or smaller) into a (Star Wars TFU) pcd file...

Why doesn't QuickBMS simply reimport?

[aluigi]

Because reimporting is not guaranteed if memory_files are used.
The code is correct but users reported problems when reimporting files with scripts that use memory_files so I decided to warn the user about the experimental nature of the feature.

[cornel]

What are memory_files? I am reimporting audio files.

[aluigi]

MEMORY_FILEs are buffers, some fake files that exist only in memory and are used as temporary places where storing information and files for editing them or as "headers" for giving a format to raw files.
In the past I used them a lot for building files that were stored in chunked mode (basically a file divided in small pieces that must be reassembled in memory and then dumped to disk) inside the archive but now I try to avoid this technique when I can.

[cornel]

I see. Would it be possible to extract the chunks as they are (and then modify them as they are and reimport them as they are), instead of interpreting and reconstructing the final memory file?

[aluigi]

It's possible to update the script, maybe.
Remember that chunked files in reimport mode are ever a doubt even if dumped directly to disk for various technical reasons.
What's the exact script you are using?

please use ever the official links when possible (I replaced the code with the link for you).

Let's try the following modified script:

Reimport gives an error...

[aluigi]

try with the following line at the beginning of the script as suggested (the script is a header builder indeed):

Code: Select all

quickbmsver "-."

[cornel]

Now there's no error message, but the injected audio file is ignored by the game and the original audio is playing.
When extracted, the modified audio file is indeed present in the pcd container file, but it turns out to be a blank (no sound) wav file, so somehow the injecting process erases the audio data from the file...

[aluigi]

I will check the method again for quickbms 0.8.5 but I'm quite sure it worked perfectly when I implemented it
