Police Officer Smith is an adventure game developed by Arnold and Rockin-B for the 2007 C4 Sega Saturn homebrew competition. As with most Saturn homebrew, it's very rough and incomplete. Nevertheless, POS is quite impressive from a technical standpoint. Right off the bat, you'll notice it runs at the Saturn's highest resolution. While the graphics aren't extraordinary, they do have a crisp, clean look. Rather than CD audio, the game's music is synthesized internally via the Saturn's soundchips. Most remarkably of all, it utilizes both of the system's CPUs, a feat rarely seen in even officially licensed third party Saturn titles.
Police Officer Smith can be run on actual Saturn hardware or emulated through SSF or Yabause. If you got a few minutes to spare, I'd say it's worth toying around with. You can grab a copy at the link below:
