I am using a 60GB WD Passport as my external Wii HD. I tried looking for the answer to my question, not sure yet. I want to know how to get games to their smallest WORKABLE forms for backing them up on another external and playing them using a USB Loader. I copied my Fire Emblem Radiant Dawn to my external using the wii and it installed as 3.05GB. I extracted the iso using WBFS Manger 3.0.1 as 4.37GB. I just downloaded Wiiscrubber 1.4 today. I understand that scrubbing it allows you to compress it into a .rar or .zip using less space. Do all scrubbed games work 100%? (I have read there is some debate on this question) Does scrubbing an iso make it install using less space on an external? Do trimmed games work 100% when played? (Fire Emblem trimmed iso is 2.90GB) It worked! Does it help further to scrub and trim an iso together? Thanks! I plan to test these questions out myself later when I can actually play my wii.
