For those looking to revisit their favorite Wii U games or experience them for the first time, a popular option is to use a Wii U emulator like Cemu. Cemu is a free and open-source emulator that allows users to play Wii U games on their PC. One of the most critical components of using Cemu is finding and using ROMs (Read-Only Memory) of Wii U games.
To get the most out of your Wii U ROMs, you must configure Cemu’s graphics settings. Default settings often cause stuttering or lower framerates. 1. Graphics API: Vulkan vs. OpenGL

Despite the legal friction, the argument for preservation remains the strongest defense for the existence of Cemu and Wii U ROMs. The physical media of the Wii U, specifically the proprietary high-density discs, are subject to disc rot and hardware failure. As functional Wii U units become scarce and expensive on the secondary market, the original experience of playing these games is at risk of being lost
This is the only strictly legal method to obtain ROMs for games you own:
