Technos Double Dragon 2 arcade pcb repair #2

I bought this board non-working and it arrived with the main RAM missing on the top board and two sprite RAM chips missing on the bottom.  I soldered in replacements and.. it worked 100%!  Nowadays this is a very valuable game for someone to scavenge for quite cheap RAM parts, so I assume it had been removed years if not decades ago.
