About LLE emulation

This is something, what wasn't mentioned before. Now devs agreed, that there is no reason to keep this private longer So, how it's working:

1. First, you need to dump firmware sprx modules from your PS3 console (/dev_flash/sys/external), and place them to rpcs3\dev_flash\sys\external directory.
2. Then you need to decrypt them, also possible using RPCS3 (Boot ELF / SELF file).
3. Open "Config -> LLE Modules Manager", and select modules, which you want to LLE'd.

I have a problem, LLE not read folder "dev_flash\sys\internal", Yet it is as important as the external folder.

What do you mean it doesn't read it? The module .sprx's go in the external folder, as BlackDaemon explained.
