Partly. From a very quick view it seems the register emulation works very simliar but the graphics output side seems to be different. Riva is pretty old, right? Something like 15-20 years? What capabilities do these cards have? 3d accel? Or 2d only? Which features are emulated? Which features are actually used by modern linux? cheers, Gerd
