@Naruto06 : If you have any trouble don't doubt to tell me.
I've just finished a little XRG set (take in mind my new monitor is 1920*1080...). For those who want to learn.. well, I don't really feel like writing a tutorial, but you can download gauges and observe and experiment. In addition, I'm attaching a blank .ini (gauges.ini.rar), a template, that is. All you have to do is fill it to suit your needs (in case you don't know it's opened with Notepad). Btw, some basics :
-You must have a folder under the LFS folder (by default C:\LFS) called "Gauges".
-To create a new set you must create in the "Gauges" folder a new folder called "GaugesXXX", XXX being the name of the car. For example "GaugesXFG".
-Graphic files must be .tga (targa format, one of the first image formats ever) and obviously in the GaugesXXX folder.
-File names for images are : "rpm" "rpmneedle" "kmh" "kmhneedle" "mph" "mphneedle" "turbo" "turboneedle". There's a little bug and the background must be called "backround" instead of "background".
-There must be an .ini file called "gauges.ini"

Hope its helpful, and here goes my set. (Image is obviously cropped)
