maya,

Are you really asking us to reverse assemble your project?

For instance:

X8a68:
16 bit add to 32 bit accum
6AH|6bH + 55H|54H|53H|52H

X8a82: 32 bit add to 32bit accum
5BH|5AH|59H|58H + 55H|54H|53H|52H

unlabeled sub:
16 bit subtraction from 32 bit accum

55H|54H|53H|52H - 5CH|5dH
;
X8ab6:
32 bit subtract from 32 bit accum
55H|54H|53H|52H - 5EH|5FH|60H|61H

X8ad0:
two's compliment of 32 bit accum.

It just continues this way. Building routines for the main algorithm.

The unlabled routines? Are they in use? if not ignore them.

You can ref all the techniques on this site and others. You have some work but it looks very do-able.

regards,
p
