i installed a version of Patchmii with Libdi so that i could watch DVDs on the Wii. i also just installed another version of Patchmii with the Shop Channel updater so i could access the Shop Channel without updating to firmware 3.3v2. did the second installation of Patchmii just replace the old version or do i now have both installed? if Patchmii, Libdi, or the Shop Channel updater ever become problematic, is there a way to remove them from my Wii system? this whole Patchmii/cios thing just kind of confuses me.
