This modification showing mountain ranges on both mini-maps was originally applied in the now obsolete FF3Edit editor when you save the ROM. Since those new mini-maps take more space, WOR mini-map was stored at F0/0000 when saving. With the patch, all subsequent compressed graphics after WOB mini-map are shifted and some of the EF/FBC8 free space is used instead.
This patch is a good way to have this FF3Edit feature without taking the chance of corrupting your ROM. The changes are done in a more logical way, freeing the beginning of the $F0 bank.
Since the original FF3Edit code did not take into account the Sealed Gate Continent rising, an app has been coded to fix the bug and work with custom maps.
Mini-Maps Upgrade 1.2
---------------------
This patch modify the mini-maps like FF3Edit does.
However, FF3EDit does not take into account a color switch for the Sealed Gate that has
different colors in order to mask it with the water color after the continent lifted up.
It also does not take into account location masking for the Sealed Gate entrance, resulting
in a white dot in the water. I altered slightly the palette.
I had to sacrifice a color for the Sealed Gate continent, so 2 color are reassignated to color 8.
This does not make a significant difference. I had to do this to have a matching location color
I would mask, it was a tough choice between the two but figured on a custom map the choice I've
made could have been the obvious one to do.
An app doing the same job as the patch is available for custom maps:
