A slight correction is in order. The CPU *requires* word boundaries for
data types larger than one byte. Trying to read/write a 16 or 32-bit
value at an odd address generates the M68000 Address Error exception
(in other words, you get a fatal error).
Some members of the M68000 processor family can access word and long
data at odd addresses, but the CPU in the Dragonball is not one of
them.
