Really you can't hope to do anything in C++ until you learn C++. Make sense?
I wouldn't recommend learning it only to make a gamehack, but it can be very worthwhile years down the line. It's a good skill to have.
If your going to learn C++ personally I recommend you go out and buy a $25.00 book on the basics of C++. As you can see it's not really an economical choice. Your better off just buying hacks if that's all you want, but if you really want to learn how to code you'll find the knowledge you have gained can't have a price put on it. Poetic right?
