How to remove/wedge-vicks and m. tek armor?

I can confirm it doesn't work with ZoneDoctor. Also, I get an error when I reopen the ROM with the editor. However it works manually, I loaded the intro after modifying this:



Now in your case, you're skipping right to Narshe. If you modify nothing in that event, You'll have 3 Terra riding a magitek armor. The Narshe Event start at CC/9A4F. Try modifying little by little and test as you go. I suggest you do your modifications manually as ZoneDoctor doesn't seems to be the most stable editor.
