Hey RonS, when you mention "at offset 0xBEC64", do you mean a line number? I have opened Navi.exe on an editor on my computer but I can't even seem to find the line "05 00 00 0A". I have a Z140BH. A response would greatly be appreciated.
EDIT: Nevermind I read another post and found that I had to use a Hex editor! All your posts are really helpful!
