I am a FIFA series fan and want to start making unique mods for the community for we can enjoy it more. But there is a chance that I will have to modify the assembly code (machine code) of the game during runtime. I don't know if this is illegal or not? It is the only thing that stops me now. I made a realistic youth system for FIFA 14 but I was the only one who uses it because I did not publish it. Now I want to share my mods with the community. I want a confirmation about this issue. Thanks guys
