About LLE emulation

Thanks for your answer. Just to note, edats are automatically decrypted to dat and put in place of edat.
Sdats and srpx have to be manually decrypted, renamed and copied over.

SDAT decryption is currently not supported.

About .sprx decryption - I might be wrong, as I don't exactly know much about the .sprx decryption, so feel free to correct me. AFAIK, the .sprx files are going to be only decrypted on the fly, if the game loads tries to load a .sprx and it's encrypted, but support for even loading .sprx's in HLE isn't there.

And automatically decrypting OS .sprx's doesn't make sense, as the games should never load them. If you want your OS .sprx's to be decrypted, you're going to have to tell RPCS3, that that's what you want. We can't and shouldn't go on a rampage of decrypting all .sprx's we find in your filesystem.
