I was wondering if it is possible to retexture the entire games zones to a higher res better fidelity version. I know this is possible i've seen dats in the past modifying zone textures and people hex editing in higher resolutions. Character models and mobs hold up very well to this day, just they have to run around in areas that look like PS1/N64 graphics.
Just no idea what tools can find extract and replace them for areas.. At least i cannot find any tool spoken of, there is one for viewing zones but i just cannot get the thing to work.
I doubt square will do this any time soon because of PS2 / XIV even though its completely possible to optimise and upgrade the graphics of the PC version without screwing up any kind of compatibility (same thing as dat swapping really).
