Hi guys, I would like to know if anyone can provide me a tool to recompress this graphic file https://drive.google.com/file/d/1xlxfBN ... p=drivesdk
This graphic is in TIM2 format, and is from Fatal Frame II PS2. This file originally after extracted from the game, is compressed, the header when the file is compressed is "LESS".
I use this tool to decompress it https://github.com/wmltogether/ZeroUnpa ... DeLESS.exe
I can view it with the "Texture Finder" and the "Optix Image Studio".
But the tool only decompress, but don't make the inverse process (compress TIM2 to LESS again)
I need recompress the file to insert it edited in the game. Later I will post a sample of this same file compressed.

Link with the same LESS file above, but compressed https://drive.google.com/file/d/1FIptWt ... p=drivesdk

here is bms script to do the same as that "DeLESS.exe"

Code:

# script for QuickBMS http://aluigi.altervista.org/quickbms.htm

comtype lzss0
get NAME basename
string NAME   .LED
get TOTAL_SIZE long
idstring "LESS"
get UNK long
get CHUNKS long
get DATA_OFFSET long
get UNK2 long
get ZERO long
get TOTAL_ZSIZE long
for i = 0     get SKIP short
    get CHUNK_ZSIZE short
    savepos TMP
    goto DATA_OFFSET
    do
        get CHECK byte
    while CHECK == 0
    goto -1 0 seek_cur
    savepos DATA_OFFSET
    append
    clog NAME DATA_OFFSET CHUNK_ZSIZE TOTAL_SIZE
    append
    math DATA_OFFSET   CHUNK_ZSIZE
    goto TMP
next i

and here is bms script to extract the tm2 textures from the LED file

Code:

# script for QuickBMS http://aluigi.altervista.org/quickbms.htm

get FILES long
goto 0x10
for i = 0     get OFFSET long
    savepos TMP
    goto OFFSET
    goto 0x10 0 seek_cur
    get SIZE long
    math SIZE   0x10
    get NAME basename
    string NAME   _
    string NAME   i
    string NAME   .tm2
    log NAME OFFSET SIZE
    goto TMP
next i

both scripts should be available for reimport with Quickbms

seems like an illegal operation. may not work with the ps2 disc filesystem. reverse compression is not predictable. modifying a file changes the compressed size. if it's bigger it should only re-import the part that fits in the total_size of the original. with the rest potentially missing and failing to decompress correct in-engine. re-importing a file that compresses smaller should crash the compression algorithm on eof, reading further to fill the compressed total_size.

Thankyou very much Acewell!

Hi Acewell, I made some tests, the script reimport only the tm2 files to the LED file, but the reimport mode won't work to recompress the LED to LESS, and the LED file is in the original size.
Can you create a tool to recompress the LED?
The script says that the algorithm used is "lzss"

sorry i don't make tools, if reimport doesn't work there is nothing more i can do.
that "deless" bms script was just for fun anyway.

Thanks, having the tm2 textures is
already a breakthrough. In
my translation of this game
is only missing the graphics,
the texts are almost 100%

Hey Acewell, can you make for me an Text Exporter/Inserter for this file? https://drive.google.com/file/d/1MLDtrh ... p=drivesdk
You can see the texts using the Windhex and the table file included.

i think swuforce is the guy you want, i don't deal with text.

He tried to make, but said "it's to complex". This text file uses absolute pointers, ex: 45DA01>01DA45 and so on... I've translated some texts using the Windhex, the problem that is are manys texts and many blocks, have blocks with 200 pointers, are 66 blocks. If anyone make a exporter/inserter, will make easily the my translation.
