I was wondering about this too. The Gamecube iso/gcn can be opened with Icarus/paradox GC-tool to display the file structure; ultimately what’s needed is a “Wii-Tool” sadly as pointed out above this is yet to be done. What I don’t understand is by what processes are we able to 1) remove/block any firmware 2) change the region given that we can’t explore the wii/iso file in the first place?
I’m obviously missing something here but I thought the only way to alter a single file such as an iso/wii/gcn would be to unscramble it to its raw structure add/remove what ever then recode to the desired format. If this is so then doesn’t a tool already exist in one form or another that has the ability to do this? Essentially what I would like to know is how wiibrickblocker, regionfrii, and unscrambler manage to interact with the iso/wii file if, as you say, we can’t?
