I'm on a 3.3U Wii and planning to update through ModMii. However, I read that I need cIOS249 to play some games I'm interested in. So can I simply install cIOS249 when I'm updating by installing the WADs from copy_to_sd/WAD? If so, what WAD(s) should I remove from the WAD folder so that they don't "overlap"? Thank you.
