well, I extracted a brand spankin' new common5_en from my Brawl iso, went in, extracted Mario's first texture, and replaced it with the same one. I went to save the file as a new common5, but no dice. I don't get an error message, the program simply stops responding. Is there a specific file type I should be using? I have tried both .png and .gif neither seems to work.
However, if I simply save the file, and not try to create a new common5, it takes a good minute, but it does save and it works fine.
