Check your original PCB, does it have ROM @ U12?

And check the contents of the mods you copied off, do any contain the words "NOT INIT"?

your native pcb is 1590 with rom and the one your replaced maybe have rom (U12) ? if the one you replace have rom you can't generate rom with salvation tools from modules . you have to swap the U12 from the original pcb to the donor pcb or flah the U12 ic with programmer

I notice that in other forums people are reporting that some ROYL drives don't have MOD 107, and that this prevents SD's tool from rebuilding the ROM. Assuming the other MODs are OK, then AFAICS it should be possible to reconstruct the ROM image using the MOD 0B data embedded within MOD 109, near the end, just before MOD 0A. In fact I believe that I could do it by hand. If that's too difficult for you, then you could easily convert ROM MOD 0B to SA MOD 107 by recomputing its length and checksum bytes, and then padding the sector with zeros. I could do that for you as well.

Here is an example where several MODs are "NOT INIT":
