im useing wimage u wont belive how ez it is to do with this prog u make a iso useing dvd decripter then u load winmage then open iso then u can do what ever u want to this iso just like if it was on ur hdd now u just look through the folders and find the dnas271.img file which it will stand out cause it will have a floopy disk icon when u find this click it and use the inject button at the top of the screen on winmage now u can put a new file in its place just put the patch file in place of the old one when done exit the prog and burn the iso its simple as that
