Uhh, those are storage formats, not a type of data file, you .rar or .zip something to compress it and transfer it, then the WinRAR and WinZIP programs unscramble them and restore them to their original state.
Im sorry, im trying to transfer them from my PC to my Wii but they wont even appear on my Wii, some say there rar and some say there wad , so I really have no clue what im doin D:
Right,so I need a hacked Twilight Princess game to do it...well I was planning on getting it anyway I guess this will push me to get it, thanks Muffin Man :D
