<!--
Offset of program relative to CROM base: 0x600000 (0x200000 in the
ROM itself). Inexplicably, at PC=AFC1C, a call is made to FC78, which
is right in the middle of some totally unrelated initialization code
(ASIC checks). This causes an invalid pointer to be fetched. Perhaps
FC78 should be overwritten with other program data by then? Why is it
not? Or, 300138 needs to be written with a non-zero value, it is
loaded from EEPROM but is 0.
