How to Create own BM Files ?

Hi

i have some problems with Create a Custom Loading Screen with WDFUSE 2.6 Beta , while TFE have some problems with German Loading Screen , not with English so far. !

i have first convert my Pic in BMP 320x200 (8Bit Coulor)

Then convert it in BM , but the Graphics ingame are Wrong !

Now i have find out , the Wait.bm use a .pal File

I have Tested this with the Boba Fett: Episode Assassination on Nar Shaddaa Map , first just Extract the Wait.bm , to see the same Error , then extract the Wait.pal File , and well Done 

So i know i need a Correct Pal File Set for my Pic. or the BM File  !

How to Create or Auto Set a Pal File for a own BMP Picture or BM File , which shows the Correct Colours ?
