    Killer Instinct hardware

    driver by Aaron Giles and Bryan McPhail

    Games supported:
        * Killer Instinct
        * Killer Instinct 2

    Known bugs:
        * the SRAM test fails in diagnostics; this is due to the fact that
          the test relies on executing out of the cache while it tromps
          over (and eventually restores) the instructions it is executing;
          this will likely never be fixed

Killer Instinct 1 / Killer Instinct 2
Rare/Nintendo, 1994/1995

PCB Layout
----------

This is a fighting game using a hard drive to hold the graphics + code, running on
what appears to be Williams Electronics manufactured hardware.
