Changes

Again, reverse engineering hasn't been finished on the first model's DSP, but there are plenty of other problems that also need to be worked out. Last I checked, Virtua Cop 2's textures just display black. Virtua Fighter 2 just freezes after a bit due to bugs in the DSP comms. Some MAMEdevs have the source but refuse to share it or do anything with it, thereby ensuring that this driver doesn't work well.
