Unlike other USB loaders the WODE fools the Wii into thinking that it is the DVD drive. WODE means Wii Optical Drive Emulator by the way. And that is exactly what it does. If you install a WODE there is no, let me repeat that no soft modding needed to play your 1:1 dumped games from a Hard drive. Sure if you want to get all fancy and have the WODEflow loader installed then you will need to have HBC and DVDx installed but that is all. Ultimately the WODE was created for those users who do not want to mod their Wii - it is really hard, if not impossible to brick your Wii if you have a WODE attached. Feel free to ask what ever questions you might have.
