I'm trying to get this excellent game 3d models (its graphics still impress me for a 1999 title).
After looking at disc file structure, file size, etc. it seems .CTS files are the 3d models container.
You can open it in hex-editor and there's a lot of .nj/.njm (dreamcast models and animations, respectively) which are both usable in Rich Whitehouse's Noesis. It's been ages since I met a documented file format with tools avaliable for them... but they are stored in hideous unknown file (sigh)
CTS appears in many file extension databases as CrazyTalkSound (obviously not) and Permanent location ConTentS file from ABC Programming Language (candidate?) it sounds possible to me.
What kind of encryption is this? Please, praying for a bms script to mass extract (no reimport needed). I upload sample, and some alternate files in case CTS is allocation table only (zip compressed upload sorry. the file extension isn't allowed).
Thank you for reading and caring.

I'll appreciate any direction. I think a structure or compression type name will do as starting point. thanks!

stm and stn are not archives, stm is very small while stn probably contains some type of audio (just my guess)

Thank you very much. Im gonna rush to try your script, be sure I will be entertained (plenty of CTS files throug 4 gd-roms!).
About STM/STN I thought that too, but Im thinkin about partitures which work along the OSBs. You made my day! marked as issue solved.
