[ ff8]field texture replacement error

[Shunsquall]

@julianxhokaxhiu @myst6re , I noticed a wrong behavior of FFNx. Some times ago(in march 2025), i had some problem to integrate the textures to the game. Actually if you follow the guide of FFnx on github, the opposite will happen: if you want to use tonberry type textures you have to disable "save_texture_legacy" in ffnx.toml. But if you want to extract tonberry type texture you have to enable it and also enable "save_texture". Another problem: when you want to extract tonberry type textures for the backgrounds, it saves it in the wrong folder: mods/Textures/field/mapname/mapname_xx.png, instead of mods/Textures/field/{2 first letter of mapname}/mapname/mapname_xx.png. Im 100% sure the second path is working. And final issue: the extracted tonberry type textures are rectangles of 128×256 pixels. But if you want to replace them, your texture must be a square with the right half side being totally transparent.
