I need to remove a bad code from my .GCT and put in a new one. I'm replacing the previous 3.5.3 with the upgraded version. The problem is, I don't know how to extract the previous code or what program to use. I know how to put codes in however, so if someone could help me figure out what the old 3.5.3 code was and then tell me how to take it out I'll be set.
