[Help Still Needed] Extract, build a packer .csa files

[godsteeth]

i hope its alright to technically bump tthis with some possible important new information?
So while i have yet to find an already existing game file unpacker that works with SSO's .csa files, i found that a game made by SSO's dev team, Pixel Tales, made Barbie Horse Adventures: Riding Camp. I already owned the game and noticed that it too had a .csa file. which made sense, theyre by the same devs! of course i kind of gave up on focusing on that since SSO's files didnt work in any extractors i have

yet, i was incorrect. my friend just opened that game's .csa file in the program Game Extractor. odd? i dont know if this info may help with understanding SSO's, but i find it strange that a game that likely uses the came custom engine, with the same custom packing DOES open while SSO's does not. id have to assume something was updated in the method but i thought i would toss the info here anyways.

So... your friend got the files?

sorry for this late reply, i havent looked into these files in a while due to no progress. but sorry for any misunderstanding, we dont have the SSO files, as in the unpacked game files, we have files from another horse game the same company used that also had the same packer extension of .csa. that is what we opened in Game Extractor, not SSO files. 
If i go to C:\Program Files (x86/x64)\Star Stable Online\PackFiles you'll see there's a ton of .csa files and .csaheader files. thats what we attempted to open, which didnt work. but, from the company's other game, Barbie Horse Adventures: Riding Camp, the .csa files DO open and i would have to guess its whatever new protection SSO put on their files to prevent hacking.

im going to try and get back into this though and see what i can find. will post on this thread again if i make progress.

Maybe it's hopeless at this point but bumping in hopes someone can still help, even if it's through PM.

its really a shame no one has come forward with info on how to do this, because its 100% possible as i have seen a Youtuber edit textures and models and put them in videos... of course, they dont want to give ANY information away. that would be too easy i guess lol
