Modifying system files via WADs carries a minor risk of bricking your console if done incorrectly. Protect your console by following these safety protocols:

Beyond functionality, there is a distinct aesthetic preservation aspect to this work. The Wii Menu was unique for its "diorama" aesthetic, where every channel had a specific sound and animation that played when the cursor hovered over it. Many hastily uploaded WAD files on the internet lack these polish elements or, worse, use incorrect banners that display glitched graphics. Channels dedicated to fixing WADs treat these files with artistic respect. They ensure that a Nintendo 64 game running on the Virtual Console displays the correct N64 cartridge graphic, or that a homebrew app uses the correct audio loop. This attention to detail preserves the "feel" of the Wii, ensuring that the user interface remains a cohesive work of art rather than a graveyard of broken shortcuts.
