...My biggest problem will be converting each entry into its respective format, But i will have to wait till sunday to see about it.

Here is a tip, there are only three formats

        if( $index->{param_fmt} == 4 ){
            $index->{value} = decode('UTF-8', $raw ) ;##utf-8-special 
+NOT nul
        } elsif( $index->{param_fmt} == 516 ){
            $index->{value} = decode('UTF-8', $raw ) ; ##utf-8-charstr
+ing-nul 
            chop $index->{value} ; ## chop the null
        } elsif( $index->{param_fmt} == 1028 ){
            $index->{value} = UInt32( $raw ) ;; ##uint32
        }

I havent forgot about this as it is a side project in attempts to actually finish up another project. Eventually, what i am going to do is load all the offsets and read lengths into a hash or an array, that way one can type in 'script.pl -p PS3_SYSTEM_VERSION "03.5500"' and that would actually patch the file. i have this sunday off and nothing at all planned so hopefully i can bang this one out
