Mod tutorials

[1crash007]

Is there any good pages for good modding tutorials
as i am thinking of a graphic overhaul for this game.

What are the texture limits to the exult engine?
And can any texture format other than TGA be used? or whatever it is?
And does all the editing of the game (no particular one) have to
be done in exult studio?

sorry im just curious i am a modder for a different game
when i first saw the 3d i thought of some ideas to make meshes
but since it isnt anymore i then thought of new textures.

And another thing are the images 8bit 256 color or higher?
