Nah mate. They had it right away. They just had a tighter knit group using it. Eventually they got tired of it and shared it. Then someone reverse engineered it and added their little touches. Make no mistake though, it's been there.I have been aware of a "Trainer" for quite some time, when the 32 bit version of Elite was abandoned by FDEV, it took the hackers a long time to make a updated 64 bit version of the trainer. It's out there though and more and more are using it. Personally I have encountered people who rarely come into open and forget they had the "Hacks On" then flick the switch when someone noticed. It's becoming more and more commonplace now.
At first the Premium ammo accusations started flying but then people got to thinking and this explains many a situation.
