If I'm correct, you can transfer this map over to the final Version using Explicit Paste. Open up the pre-release rom and 1999 AD, then leave it there. Open up the FINAL version of CT, and load another overworld map with 1999 AD. Explicit Paste for Layer's 1-3, Most recent copy, and properties on both maps. Now, rightclick and drag the areas you want to copy over and take it bit by bit into the final version of CT's map. Once done, close the pre-release 1999 AD Map, and then save. You should have it in there.
