Hacking Issue with brawl and usb loader

[phillyrider807]

Ok the game does work. Online and all. However the game is bigger then it should be. I wiiscrubbed my brawl disk to cut out subspace and the iso comes out to 4.36gb. However when installed to my usb drive it's over 6gb. How can this be? It makes no sense. I only have a 8gb flash drive and im not able to add another gane the usb drive says i only have 0.47 gb left. When i click properties on the .iso on my desktop it says 4.36gb. So what happened between sending it form my desktop the the flash drive? I used wbfs 3.0
