It looks like it's the modified version of the .SPR file format of
Secret Files: Tunguska and Secret Files 2: Puritas Cordis
The files are partially encrypted with a KeyNumber, which is game-dependant.
See the SPR description here: http://wiki.xentax.com/index.php/Secret ... nguska_SPR
If you send me the game EXE file, I'll try to find the actual KeyNumber.

I couldn't use the EXE file, because it's packed/protected. But, I made a brute-forcer, so I got the KeyNumber: 0x08A0DC
I also created a primitive SPR extractor. Usage: LostHorizon_extr.exe <SPR_File> <TargetDir>

@bacter: Thanks for publishing the key domain value. As I had already deleted my brute force tool used to get the Secret Files 2 key, you saved me the hassle of doing this all over again.

I have update my SPRExt application accordingly to support Lost Horizon as well. Also, since Lost Horizon uses the SSHC compression method in its data files, I have added support for this method as well. The Secret Files games use this method in their save games, which means that these should now be decompressable as well.

If you find any bugs in the tool, please let me know.

For those interested, the format news have been roughly documented at the wiki page quoted above.

Best wishes,
Deniz

Thank you Deniz for releasing the SPRExt application with the source code
I have to say that it's working great under Wine.

And also, thanks bacter for the key domain value

[Deniz Oezmen]

Thanks for the feedback! Glad to hear the program is accessible despite my platform choice.

Best wishes,
Deniz

Interesting. How do you get the modified files back into the game? Do you have a repack tool or does it suffice to simply place the files outside of the SPR archives into the correct directory?

Yes,simply place the files outside of the SPR archives into the correct directory.
Extract the loca.spr and copy data folder to game root,and remove loca.spr from archives.ini like this:

[Archives]
ArchiveFileCount=5
ArchiveFile0=data.spr
ArchiveFile1=music.spr
ArchiveFile2=music.spr
ArchiveFile3=video.spr
ArchiveFile4=data_patch.spr
ArchiveFile5=loca_patch.spr
ArchiveFile6=video_patch.spr
ArchiveFile7=music_patch.spr
ArchiveFile8=data_patch2.spr
ArchiveFile9=loca_patch2.spr
ArchiveFile10=music_patch2.spr

[bacter]

There's another way. You can make your own .SPR file and put it to the end of the list in the "archives.ini".
Example:

Code: Select all

[Archives]
ArchiveFileCount=7
ArchiveFile0=data.spr
ArchiveFile1=loca.spr
ArchiveFile2=music.spr
ArchiveFile3=video.spr
ArchiveFile4=data_patch.spr
ArchiveFile5=MY_MODIFIED_FILES.SPR
ArchiveFile6=THESE_ARE_MY_FILES_TOO.spr

This is my very primitive .spr maker (originally I created to the Secret Files : Tunguska)
It's a work-in-progress version, there's no SLZX, SSHC or any other kind of data compression,
but it works. (At least it worked with the Tunguska games)
