Editing files with Brawl ISO only?

[yadayada]

I need to edit files without using the SD loader method, and instead going back to the old days of editing the iso. My Wii broke, so I am restricted to emulator play and require an iso editing tutorial. If someone knows where I could find one, please point me in that direction.

Get Wiiscrubber, remove the masterpieces partitions, expand the game partition to the maximal size and do whatever you want.
