Hey. so the url blocking isn't doing a very good job. Back when I had the whole Wii U blocked by MAC address, things were ok. Online couldn't work, but no stupid update prompts. At one point I decided, what happens if I keep just the URL blocking but no MAC blocking. It was ok for a little bit, but not anymore. Now it is aware of the update. The system update can't download because of the url blocking. But MarioKart has an update or something which won't install without the system update. It's being really annoying. If the MAC blocking is off, after you refuse to allow the system update, it won't even let you play the game. With the mac blocking on, it will eventually say, start anyways. How dd the Wii U figure out there was an update? The URL block list is missing pieces. Anyway to get rid of these prompts? Do I just have to keep the MAC filtering on all the time, and let it try to update, and wait for it to fail to be able to launch my games? Nintendo has no right to mess with you trying to play games in offline mode. This is not cool.
