This is the version to run the first (trivial) infinite loop
correctly. I hacked up the loader slightly to replace one of the
(nonexistent) pages with a static byte array.
z80 code executed:
$4000:
JP $4000
4000 c3 40 00
4003
This version also draws the opcode executed on the screen, to aid in
debugging the emulator:
move.b d0,$4c00+32*(128/8)
Also, it turns out that I was mixing up the emulated SP (a4) and emulated
PC (a6). That has been fixed.
Further, it seems that movea defaults to a word operation in a68k.
This led to pointer corruption, which has been fixed.
