Its not anti-piracy control, just to clarify.
Also people talking about ARM7 switches causing problems, well guys of course it is. You are taking a whole part of a game and replacing with another its not going to work fully. Someone will have to compare various ARM7 binaries with the GTA one and find what actually is the problem, not just guessing and randomly switching them around. The wifi part of it obviously needs to be left original but whatever part that makes it not boot can be replaced with another games ARM7 (unless they are related).
