major changes to the emulator

I have ported the emulator over to C++, so now it can run at the correct speed, and there have been some semi-major changes to the video card. namely, changes to the color indices. I have hidden the older downloads for the emulator as they will now have minor incompatibilities with anything made for the newer emulator. the new emulator isn't entirely finished yet, but I wanted to make an announcement now just to let you all know.
