NOTES:
       Several ROMs are identical (there are 2 identical graphics engines, and one romset per graphics engine)
       Several ROMs are flagged by ROMCMP as ...
                                                 1xxxxxxxxxxxxxxxxxxxx = 0xFF
                                            or     1xxxxxxxxxxxxxxxxxx = 0xFF
                                            or     11111xxxxxxxxxxxxxx = 0xFF
       I don't know the significance of this, but ALL ROMs were read *many* 
       times to verify their contents.

[Jul/20/2002]

Alternate read of Prop Cycle WAVE ROM A

read 1 = pin32 tied to GND
read 2 = pin32 tied to +5V

both reads have 00 in all even bytes
