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

[Matryoshka]

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?
