If you have 0.8.5.0, only use the MTL.I downloaded the Text Project and MTL files, how can I install the "Eng" patch now? Im new to this so no prior knowledge available...
If you have 0.8.4.3.1, extract the Text project archive so that the text folder within overwrites the text folder in the game files, run the MTL tool, launch the game and change the language to MTL.
As for the English patch, forget about it as it is not up-to-date.
