FFTactext won't patch[PSP]

[Justice]

I keep getting the "DTE for WORLD.LZW failed" error.
Already tried changing the text and even using the original text but nothing seens to work.
Also tried saving and openning the patch to patch the ISO

I don't think FFTacText works with WotL.

How come? You have the option to import a PSP ISO... or does that mean nothing?

Either it's not fully supported or I'm just mistaken.
