    Hello everybody. I've created this thread for trying to decrypt SSB data. I'm not talking about decrypting the Romfs, I already did that. Inside Romfs there are 3 folders. One with the music other with the tutorial video, and the other with static.crr file. I've already managed to converrt the music (nus3bank) to IDSP and then, to wav. However, there is a 900MB file, apparently encrypted, called "dt". Also, there is a file called "ls" (encrypted too) and then, static.crs and a sarc file called cro.sarc


    I really think that the crr, crs and cro.sarc files are for decrypting "dt" and "ls".



    Any ideas here.

    crr, crs, cro.sarc have nothing to do with it.

    ls describes how stuff is stored in dt.

    ls = list

    dt = data.

    Anyway, it's not encrypted, just compressed.

    Does anyone know which commands to use for the smash-stuff?

    The readme and GitHub page do not list them.

    I think each py file just does something different. The one you want is probably dtls.py. Try running it in the same directory as dtfn and lsfn.

    Just to kindly ask, has anyone still got UnNUS3? As the old link doesn't work anymore.

    Either that or has anyone got the file nus3bank.bms? which is used with QuickBMS.

    All of it is on the Sm4shcommand thread. Basically, burn through all thirty pages of it immediately.

    Nope, but you can use other way to use the extract dt and ls (not HANS)
