I just tried your solution but with one change. I Used the Wii Backup Fusion app to transfer the ISO, then I used NKit to recover to ISO. Now the file is back to original GC specs. Maybe a little quicker and less complicated this way. For me at least. ;-)
Thanks for your help.
Only thing drive me crazy is all these new horror games nowadays is its so dark, all time. I can't even play them. I understand they trying to create spooky but be creative a little, not just darkness with pop out scare scenes.
