I've tried uninstalling the Quadforce wad through my Wad Manager program, but it refuses to let me do so, giving me a message that reads "ERROR! (ret = -1017)". It gives me the same message when I attempt to reinstall the wad as well.
For your second suggestion: would you be willing to link me to a reliable walkthrough regarding this particular formatting process( unless you would rather walk me through it yourself. )?
And I've tried using the Wii Iso Renamer but all that happens when I drag the ISO file over the .exe application is a window pops up that allows me to open my desired ISO, but when I do so, absolutely nothing happens. Did I possibly install it incorrectly?
