Hi guys, it would be nice to have all the Star Ocean 5 images and textures extracted, but I really don't know how to do.
Maybe is very similar to the encryption of Star Ocean Anamnesis (SLZ), but the quickbms script don't work at all, there something different.

Here there are some AIF files of the game PS3 version:

EDIT 02/05/2019

And here there are ALL the AIF and ASF files of the PS4 version of the game, 6.36 GB on mediafire, sorry I don't have enough space on mega and even gdrive :roll:

If you need only some little samples just to test, there are 2 files in the zip on the attachment.




Thanks in advance :)

Files are not encrypted, but compressed. Mostly SLZ type 2 and 3 is used, so I would guess it is more similar to older titles than Anamnesis which uses mostly type 7 (zstd). Still the type 3 code for ps2 games doesn't work meaning they changed something. Judging from the type 2/3 in older games, I would say it is a LZSS variant.

This was discussed in couple of other threads before, but I don't think anyone got it working. Basically there wasn't much interest. Last I know is that chrrox dumped the decompression method from the RoF executable (it also used type 3 mostly if I remember correctly). Still I never got it to work as is. Hope someone figures this out someday :D

I edited the first post with an attachments. Contains very little files, AIF and ASF, just in case.
My research on this type of compression is failed several times, I already asked on Xentax forum, I know this is very difficult, sorry for the request. I still hope for someone someone figures out to this problem.

OT (But exctracting things from tri-Ace ps2 games is more difficult hahahaha, and there are no tools. My dream is to obtain the MPEG video files of SO3 and VP2, because I have the intention to remaster them in 4K resolution with a Deep Learning software, but I need the source files first...)

I have posted the SLZ type 3 decompression code here : viewtopic.php?p=45696#p45696

Speaking of VP2, I have also released a tool for the VP2 models/textures on xentax. I don't now much about video files though.

Oh, thanks, but sorry I am totally noob, how can I use this code? I tried "SLZ Decompressor v1.1", edited the slz.c with your new code, but didn't work. You speak about quickbms, I'm really confused.

edit: I tried to compile it with visual studio and other tools, but there are too many errors. I can only use quickbms but I don't know how to convert the C# language to BMS

my knowledge of these things is really embarrassing...
