Please tell me you are joking...you don't know the first thing about reverse engineering. So less, you didn't even know what it was until I told you. But no, 2 members from the Xbox scene did it. Without their release, you wouldn't even have it, nevermind sell it. I'm currently on the Ps3 browser, but when i get on my phone ill post some interesting logs

And too the other guy, no it's not a competition...but without the Xbox release no one in this entire scene would have this, selling something you didn't create is stupid and selfish. He's basically just convinced everyone he created what he is selling, making him a rep whore.
