When Expendable was out, there comes a patch for support of the EMBM. The Matrox G400 series were the only cards in 1999, that support this feature in hardware! You can't start the game with the official EMBM Patch on non Matrox G400/G450/Parhelia? cards. Also when they support this feature.
There is an option, to play Expendable with Bump Mapping on Non Matrox cards, that supports the Environmental Mapped Bump Mapping in hardware! A inofficial fan patch makes it possible!
