> What platforms in MAME uses S3 ViRGE PCI interface?
This is a good question. Savage Quest uses a S3 Graphics VGA. In the source it says S3 Trio64, but not a ViRGE. The MESS driver pcipc.cpp is the only driver in MAME which uses a S3 ViRGE. But i think one of the other PC Arcade games use also S3 or S3 ViRGE.
