Link said nobody (I think this includes you) in J2HG knows C++ very well, also, even if you did, I highly doubt you can easily fix it. Why? This is because you cannot just search for a particular piece of code and then edit it in this case. Again, why? The guys that worked on it were professionals and thus it was made according to their standards. So, what if it was made according to their standards? This means they don't have to make it newbie-programmer-with-mediocre-knowledge-of-C++ friendly and I seriously doubt if they went out of their way to do that.

Krezack said that it would probably take you a month to work it out, I say it would take longer, much longer because it wasn't made by just one person and also, the ones who made it were professionals with extensive experience and knowledge on programming.

Example:

Excel knows C++ but he doesn't know it very well. I give Excel a C++ source file (source code) that's around 2000+ lines long (The JJ2 source code is a lot longer than this, mind you) without any comments and with cryptic variable and function names. What do you think will happen? I'm guessing that Ack won't understand one-fourth of what is written there because, number one, he doesn't know most of what I'm talking about, number two, even experienced programmers will have a hard time understanding something very cryptic that they did not make themselves.
