If its freezing it could mean one of 3 things:

You need to run it with different settings: try internal/bdmirror or external/bdmirror.

Or its got protection on it further in and more modifications will be needed to the eboot/selfs/sprx's to make it work.

Or it's a bad rip, and it will never work.
