Warnings

If you have followed the OLD guide you need to rename the original
CA27.cer to CA27.cer.bak and (my) CA24.cer to CA27.cer
and you have to restore the old CA24.cer , by renaming
CA24.cer.bak to CA24.cer
This is needed since some games use the original CA24.cer
If you lost original cert, you can take it https://github.com/downloads/drizzt/fuckPsn/OriginalCerts.zip
