The main problem is that the EXE header generated by the cc65 runtime
lib is wrong. It defines a single load chunk with the sizes/addresses
of the LOWCODE, INIT, CODE, RODATA, and DATA segments (the whole user
program).
<p>
The contents of the EXE header come from the EXEHDR segment, which is
defined in crt0.s. This cannot be changed w/o modifiying and
defined in crt0.s. This cannot be changed w/o modifying and
recompiling the cc65 atari runtime lib. Therefore the original EXE
header must be discarded. It will be replaced by a user created
one.
