I remember coming across a Google Drive Repository From A User Named mrt84. He had a Google Drive folder of Wii Channel WADs like Flash Game Injects, YouTube Video Injects, Simulators and More. However The Old mrt84 channel got hacked in 2022 due to him accidentally clicking on a scam link and the repository was gone. Here an archive of his old channel: youtube.com/@redfirestudiosmrt84archi-gs1gy?si=Y5QRGgvIM9ZtgGyN mrt84 was kind of popular at the time so maybe these were saved.
