i'm guessing it'll decrypt all the encrypted modules, files and stuff like eboot.bin, so there probably won't be any need for replacement drivers that still lack functions or have them set up incorrectly.
or, alternatively after they're decrypted the emu authors can learn more about them and implement everything they're missing in their own versions.
