I've recently begun work on redrawing the in game maps. By default this is a relatively simple process. However I've decided to try my hand at using HQ images for the maps (i.e. 1024x1024 versus the default 512x512). The only snag in this plan is my ability to manipulate the system to get it to actually use a larger dimension texture for the maps.
Using a hex editor program I can rather easily import in the new larger image maps into the dat file as well as successfully get the dat to read with the proper dimensions and data size allocation. But, and this is a big but, I can't seem to get the game to actually display the larger image dat. What I mean is I place my new shiny 1024 file into a map dat but in game it only shows 512x512 of the top left quadrant of the new map.
Obviously this is not an intended result. I've got forum topics going over in FFXIdats.com and at Windower.net hoping someone there will find some way that I don't see. Still I figured I'd reach out here as well to broaden my chances at finding a solution.
If anyone can think of a solution I'd be extremely appreciative.
Here's a sampling of my maps:
