Sorry, I see what you're saying my apologies. Yes, you're right, 'pudink' can perform a Game title update as long as he is running Gateway 2.0b2 and using a rom from the same region as his 3DS. Since the question was posted in this thread specifically about firmware spoofing, I was worried the question was related to the system update. If you don't want to download the update for the game, all you have to do is turn your wireless off and the game will boot normally or just press A when the message appears to launch the software if you have wireless running. But yes, it is safe to perform software updates on emuNAND.
