fancy3d.lod and fb.fobl executables, foben.foc is probably all encrypted and foben.fod has a "PSH" magic but no idea bout information table and content.

*edit* foben.fod is obtained from the lzma decompressed FANCYRES\NOTIFYMODULE resource of the executable, right?

Note that the files of this archive are "weird", probably a bit scrambled/obfuscated.

Hi,.

Is the .fob file using secondary compression?
This is part of the file data, it should be a single file

But after decompression, I do not even know what this file is
I see this position is 5D000000, seems to be a type of compression

How to extract?

I have updated the script to version 0.1.2 so that you can unpack that specific fob you provided.
If it's part of an archive probably I need both the original foc and fob, but test the script on the archive first.

The file is too big, the game is only one foc and one fob, a total of 1.2G
So I only screenshot a part of the file, the analysis steps are in accordance with your 0.1.1 script
For example, the starting address of the data in 5224, every 6120*n is "USE" data...
But the number of files can not correspond to foc file.
I'll try again, thank you so much..

I uploaded both files, one fob and one foc.

By the way, I did not find the 0.1.2 script...
Thank You. .

Are you sure that ark.foc is relative to ark.fob?
Yeah I know that it seems a stupid question but foc says that the first files are PAK while they aren't, that's the reason behind the error "Error: the requested amount of bytes to allocate is negative (0x91c9e9ef)".

The only way to "fix" that is disabling the filenames but there is no reliable way to guess if it's a bad or good archive.
So, in the doubt, I have updated the script to version 0.1.2a (refresh your browser!) for skipping the names of the "ark" archive.

Hi,..

The game has only one foc and one fob.

I analyzed the result is this:
In foc there are six pak name (or 7?)
The last six files in fob are special because they do not point to the data with an offset
Fob inside the structure seems to be this:
5224: "USE" ......... (with offset address)
5224 6120 * n "USE" ......... (with offset address)
5224 6120 * n "USE" ......... (with offset address)
...
5224 6120 * n "USE" ......... (without offset address)
5224 6120 * n "USE" ......... (without offset address)
5224 6120 * n "USE" ......... (without offset address)
5224 6120 * n "USE" ......... (without offset address)
5224 6120 * n "USE" ......... (without offset address)
5224 6120 * n "USE" ......... (without offset address)
n is an integer

Excluding the last six, there are many consecutive "USE" data at offset addresses of other files.
