well the file was ISO when I extracted it, but I also tried .gmc Now I am getting little frustated. I try to explain as good as I can. FSTFIX.exe (version 1.5f) and zelda.iso (also tried .gmc) are both in d:/ So I open Run, enter cmd and write this: d:\FSTFIX.exe "zelda.iso" f t I also tried d:\FSTFIX "zelda.iso" f t And it says "file cant be found" Acording to this guide I am doing noting wrong(taken from modthatcube) Remeber that I my english is not so good so an exempel would help
