NOTES:
-*** There seems to be a disagreement in dasm with bytes like this : 0500 0307
- On one hand, you can dasm it like this : add Y1,A X:(R2+00),Y0
- On the other, you can dasm it like this : move(m) P:(R2+00),B0
- The interesting doc pages for this are the following : move(m) . A-155
- mem move + short displacement . A-139
- add . A-23
- (POSSIBILITY : Maybe Add can't have a mem move + short displacement parallel move?)
- (CURRENT SOLUTION : I'm completely ignoring mem move + short displacements for now)
-
-*** This disassembler has been 75% tested. There may remain some bugs, but it disassembles
- Polygonet Commanders' memtest code 100% accurate (to my knowledge).
