Add ability to decrypt every file in a save file.

Super Street Fighter IV has about 180 files in its save, which is [if you didn't know] humongous. It'd be great if I could decrypt all of these saves and not resort to Bruteforce and see if that works.

any real reason to decrypt every data file in the SF4 save? the only possible use-case I guess it's for RPCS3 emulator, but honestly if that's the case, just ask and push for the emulator to support the original PS3 save encryption (rather than using Apollo to decrypt all the data files)

I second this, a simple "select all" option would make this a lot less tedious. In fact, a batch decrypt of all save files in, say, dev_usb000 would be appreciated as well.

Yes, it would be nice if the emulator supported the original encryption, but in the meantime, this doesn't sound like a crazy request.
