Hi everyone.

I'm trying to write a BMS Script for Atlantis The Lost Tales (PS1 Version) to extract content from LNK Archives.
They seems to be similar to BIG FILES archives.

I'm starting from this script written for BIG FILES archives :

Code:

IDString 0 "BigFile 1.00" ;
SavePos S 0 ;
Math S  = 4 ;
GoTo S 0 ;
Get FileNum Long 0 ;
Get DataSize Long 0 ;
Get DataStartL Long 0 ;
Get DataStartH Long 0 ;
For T = 1 to FileNum ;
Get StringSize Long 0 ;
Get U1 Long 0 ;
Get Size1 Long 0 ;
Get Size2 Long 0 ;
Get Size3 Long 0 ;
Get R1 Long 0 ;
Get ROff Long 0 ;
Get U2 Long 0 ;
GetDString FN StringSize 0 ;
Math ROff  = DataStartL ;
Log FN ROff Size1 0 0 ;
Next T ;

BIG FILES example (PC) :

Code:

They seems really similar.

Similar files???

Anyway the BigFile format has been covered by the following script:

No i'm not working on the BigFile, i'm working on the LNK File (it's this LNK File i want to extract).

The LNK seems to have the same structure with all files and pointer listed in the beginning (maybe i've wrong but i found similarities between the two)

The LNK is the package format for the Playstation Version in opposite to BIGFile format for the PC Version.

What i trying to do it's to change the BMS Script used for BigFile to work with LNK Files.

Any idea what i need to change ?

I'm not work on the BigFile, it's just for the example to compare with the LNK File.

It's exactly the same game BUT in the Playstation version there are no BIGFile, it's LNK Files.

They both store the same content and same data but with different formats.

Very confusing, why didn't you just open a topic in the Game Archive section about the LNK files?
The format requires some work.

It's opened here :

viewtopic.php?f=9&t=11447

Can you try to make a script for this format please ?

Thanks.
