is there a way that I can make a new jetpack that is invisible and it functions like the SP jetpack?
This is JKA by the way.
Sure, I guess you could by changing the code.
Could I use the SDK to change that?
Ok, I know now to use the SDK, it has the info, but I would have to use C++ and I know nothing of that.
Well, you're kind of stuck then. :)
