Final Fantasy Rom Hacks

There are two different ROM hacks for Final Fantasy 1 I found that gender-swap the characters. One makes gameplay improvements, the other just changes graphics and dialog.
They each have their own unique art style you can compare in the screenshots from the character select screen.
Here is a tutorial on how to apply the ROM hack patches
