My friend Reaper2k2 has just released a new System16 emulator for the Dreamcast based on the Mame code, but drastically improved in speed and sound. Most games are running at 90%-100%! FOr those that do not know, the System16 is the hardware that some old Sega games ran on, such as Altered Beast, Alien Syndrome, and Shinobi. You can grab the release from www.dcemulation.com . Keep in mind this is just beta1, so don't expect perfect emulation, but I do have to say it is nice to play shinobi at good speed with sound on my DC If anyone has any problems getting it running, just let me know.
