“Why can’t I configure ROExt to be the window size I want?“

This is due to the client limiting itself to a minimum resolution of 1024×768. You may need to manually edit the settings yourself, using these steps. If changing your settings in GameSettings.exe still doesn’t work, try this. Go to your Talon Tales folder, then find dinput.ini. Open it up, override game window position and simply change WindowWidth and WindowHeight to your desired resolution. Leave your WindowPosX and WindowPosY as 0.
