Quake 3 Revolution (PS2) LINKFILE.LNK

Hi everyone.

Please help.

There is the resource file the game: LINKFILE.LNK

Help identify which method compression here uses.

If it is will a BMS script for unpacking and packing, it will be just super.


File: https://mega.nz/#!KxoDXDIC!zbyAO7MYx41r ... cnsEkbJvCw

Or the first 15 mb of this file: https://mega.nz/#!fsZDyDaQ!ASmNVOb1IyBh ... N_Op842f0A

Thanks Luigi, the script unpacks good, but unfortunately the "reverse pack" does not work, I'm using Quick BMS Editor GUI 2.0b

Prompt how to be ?

Use quickbms 0.7.7 and NOT these third parties old gui!
That algorithm is supported in reimporting, probably the edited archive will not work in the game, but the reimport mode should work.

ok.

I used the command: quickbms.exe -w -r script.bms archive.dat folder

"C:\Program Files\Quick BMS 0.7.7\quickbms.exe" -w -r C:\Quake3Rev\QuakeEX.bms C:\Quake3Rev\LINKFILE.LNK C:\Quake3Rev\LINKFILE\

But there is a "small" problem:

the reimport option acts as a reimporter and so you cannot reinsert a
file if it's bigger than the original otherwise it will overwrite the
rest of the archive or cannot be loaded correctly:

new size: 3214 (4816 uncompressed)
old size: 3148 (4816 uncompressed)
--------------

And so with all the files.
*The unpacked files without changes, all files original.

You can as well as and there, choose the best degree compression ?

It's the Electronic Arts most used compression algorithm.

old size: 3148 (4816 uncompressed)

You can somehow this fix ?
The degree of compression can be even better ?

I checked.
If delete the free space at the end of the original file (for example: Arial10.sfn), the file may be imported, but the problem is that not in all files have free space at the end.

The qfs_compress_data function in qfs.c contains a QFS_MAXITER value that "may" provide better rates but honestly I have never tested.
I will check it when I will work on the next version of quickbms.
