Thanks for the download. It doesn't appear to be able to convert to .spl.
I'm not exactally sure what .spl is.
The files are out of a game folder, there of the different stances a player has in the game.
Things such as weapon and armour are also shown with these .spl files.
I have been able to convert them to .bmp so they can then be edited as to what the colour or look of the weapon or armour is but then I need to convert them back so they work in the game.
