At the very least you'll be able to finally play that DS game you've paid good money for! It's recommended to switch to Tiramisu CFW even if you've hacked your Wii U before. It also has a much safer coldboot option which uses a modified version of the Health and Safety app to load payloads (more info here). Unlike Haxchi, which was the previous go-to CFW, it doesn't require you to purchase a DS Virtual Console title. Note: Tiramisu is a new exploit that was officially released on Dec 31, 2021. If you want to block system updates without a custom DNS, use this method. In the absolute worst case this can brick your Wii U.
If you don't do this, you allow Nintendo to update your console without asking. Settings > System Settings > Internet > Connect to the Internet > Select your connection > Change settings > DNS (Don't auto-obtain) Set your console's DNS to 168.235.092.108 (US) and 081.004.127.020 (EU) (use both) to block the console from downloading updates.
