Oh Man! you is confused. A wbfs wii game is scrubbed to give a nice small file. Depending on complexity of the game. A Wii ISO image file is always 4.38 GB ( a full DVD ) So you either need a PC with a reasonable size HDD or a portable HDD, If you want to store games as ISO file for burning to disc. No serious modders use discs. A 160gb portable HDD will hold approx 65 games in wbfs file type. There are tutorials on this site to help you better understand. Google it Grandpa. or be lazy link in my sig.
