Re: Karaoke File Unlock Help

Hello my friend. I've tried the XOR but I had no luck.

Just to see if I'm doing this correctly:

I XOR'd the .AUT to become MThd. This gave me the conversion hex key "63 15 3d 30". Then I looped the entire file applying this key as follows:

sz = [size of the file]
buf = [file contents]
key = "\x63\x15\x3d\x30";

for(x=0;x < sz;) {
    for(y=0;y < strlen(key) && x < sz;y++,x++) {
         buf[x] ^= key[y];
    }
}

I'm not sure if that is what you told me to try, if this is the tip, this didn't work.

I don't want to bug you, but can you point me some tool to try out? I've tried to search on the forum and could not find it.

Regards!

Carlos.
