Primary Zelda Hacking

I am in need of help of a script. What I need is a script where link goes into the past (Yes I am talking about Ages) and someone does something that changes the future, and when link goes into the future his town is different, and later he has something and stops the person from changing the future, and when Link goes back to the future, it's normal again. I need help because the tutorials on ZOSE never work, because it just corrupts my GBC file, and VBA says there's an unknown op code and won't play it. The script I need is similar to the script for Symetry village, how the past broken tuni nut makes the future horrible, but when you fix it, it goes back to normal? Its like that except it's "Past-Change-Bad Future-Get Something-Past-Change-Normal Future" if that make any sence.... :blink:

Make sure you're using the most recent versions of ZOLE and ZOSE. Next, for the map swapping, check out this tutorial:
