Yes, Chad has been more than fair when providing the informations for us. > This preset condition will not affect most games, as they're not actively > seeking out these values.

It depends on what the random number generator is used for. But I don't think, that any game out there is relying on that. And so CC is working 100% perfect. > I have however, received numerous emails asking how to make Gunfight work > on the Cuttle Cart.

Perhaps the CC incompatibility information got lost or wasn't made clear enough. May be Manuel should try that once more. But that's not an easy task, still people are asking why Thrust isn't working in Stella and I made that more than clear (I thought): It's written in the manual (RTFM!), and also on several of the download pages. > Also, as I think > far too much energy is being spent to lock it out, I'll close with this > hopefully sobering fact.

Ok, so you should publish this to the public and nobody will every try again to stop the CC. So, knowing that, only leaves the hack protection, but due to the limited abilities of most of those hackers, that's to simple to continue even talking about. :-) > ...can we stop proudly harping about killer ways to disable the Cuttle > Cart and move on? The "killer ways" I was "proudly harping about", where not how to disable CC (because we both know that's trivial), but to prevent people from removing this disabling code or the hack protection. And now, I'm moving on... :-) Have fun!
