By default the contents of this zip should go in YourEpisodeName/textplus/font, but you can put them wherever as long as you update the image paths inside the ini files accordingly.
Also you may want to change the outline color on b to the background color of your episode's message box or remove the outlines entirely; I didn't do that in the example image to show that it has outlines, but it is that way in the original PM64.
