No, I play NFS Undercover offline so there's only client side. CE doesn't help any better, I've already tried that. I believe the game is storing it differently to prevent people from making trainers so easily or the address is so dynamic it changes from one menu to the next. I use MHS to hack all my games, online and offline. CE is only used because it supports the only thing MHS doesn't, SSE instructions.
I've been around, here and there. Just been spending my free time hacking offline games, trying to learn how to find correct complex pointers easily. Some games are easier than others and this is the only one that gave me nothing no matter how I searched. Well, I'm just glad it's not the only game I have.
Sorry, I don't know where it was released exactly.
