So I haven't had much time with WUP Installer y Mod, but I've tried installing Breath of the Wild, and it did work, but when I tried launching the game, I get a message "Preparing Updates" and then I error out, and can't continue. Sometimes I'll get the option to launch software without updating but, even then I still am unable to play. I use Mocha CFW and WUP Installer y Mod. Also, is it possible to use an External HDD in place of a Flash Drive? I have a Flash Drive now, but a larger capacity External HDD I'd like to use instead. If there needs to be more info I can provide more details.
