Sorry to intrude here but, did this archive structure ever get figured out? I'm looking through the game's files myself, mainly for the backing tracks for the songs. I also seriously hope they are streams and not in the complicated psf2 format.

Sorry, I haven't had the time to look through it, and I haven't heard back from COOL12345, and I have no ideas about the compression.

I have made the unpacker now after getting access to the file today.

.STM Unpacker v0.1
Author: Mr.Nightmare™
Language: C#
Requires: .Net Framework 4.5

I tested it on DATA.STM and it unpacks fine:



File Info

.STM (Archive)
.LZ (Compressed Data) (LZ?)
.PMT (???)
.txt (Standard text file)

Once you unpack the .STM there will be tons of lz, stm files i'm unsure about the compression on the lz files though. However, whilst extracting some .STM files did error due to a size issue.

Click thanks if i helped!

Regards

Just fixed the issue when unpacking sub .STM archives it should work fine now.

COOL12345, the unpacker is done when it crashes, right?
And thank you.

Unpacker should not crash, However the extracted .STM seems to have folders embedded into the file, I have not yet found a flag which defines folders or which files are going in them, it's really inconsistent but i don't know for now.

Well, it's still a job well done.
