MESS Emulation State:
See source code for more information.
Bios starts requesting pad data so maybe we are now in the time set area ????
Need to emulate pad system, add more interrupts and get some grafix working so we can see exactly
where we are at this current time. Currently locks up waiting on (i guess) a response from the 68k
CPU. Probably need to emulate this shortly.
