/*
 F1 Dream protection code written by Eric Hustvedt (hustvedt@ma.ultranet.com).

 The genuine F1 Dream game uses an 8751 microcontroller as a protection measure.
 Since the microcontroller's ROM is unavailable all interactions with it are handled
 via blackbox algorithm.

 Some notes:
 - The 8751 is triggered via location 0xfe4002, in place of the soundlatch normally
    present. The main cpu writes 0 to the location when it wants the 8751 to perform some work.
 - The 8751 has memory which shadows locations 0xffffe0-0xffffff of the main cpu's address space.
 - The word at 0xffffe0 contains an 'opcode' which is written just before the write to 0xfe4002.
 - Some of the writes to the soundlatch may not be handled. 0x27fc is the main sound routine, the
    other locations are less frequently used.
