There is racing game on the pc (been out a while now) where you can load in the different sponsor skins for the cosworth - I found the site with the files on it by accident one night while searching for something cosworth.

Can't remember the name of the game but all the old WRC livery's were available.

EDIT : Rally Masters was the game I was thinking of :

Theres also a marlboro skin to replace the gemini one on the PC's CMR2:
