For the people that doesn't know what is it this program, it's simply an .tex (texture) file converter. For example extract Res\GuiRes\Item02.res\Item_Dhan01.tex on the same folder of converter and drag the file on DDS or BMP converter. What are the differences from DDS converter and BMP converter? Well, the DDS is the real format of decypted .TEX files (That can be displayed with DirectX Texture Tool (from DirectX SDK), you can watch all the textures on the original format. BMP converter support only 32bit textures (16.777.216 + 256transparency colors, for example the wallpaper of Dhanphir) but it miss the support of 8 and 16 bmp format (yes, i'm lazy lol).
And please, for questions write english (or italian =P), it's a pain to use google translator XD.
