I have a Shinobi pcb that I aquired and am assuming has died. I am still awaiting the arrival of my adaptor. In the meantime I was planning on taking care of the battery, etc. I planned on replacing the NEC block with a Z80 and the Hitachi FD1094A with a 68000. Now in all the research I did, the top rom board(s) didn't look like mine. I can't find the information as to which chips need to be re-burned with what files? Can someone direct me to a site that may have the needed info, or help me figuring this out?
