that's how I would have thought the object roms would be consolidated
I appreciate the replies but I'm looking for a more definitive answer. It's entirely possible that that these ROMs need to be concatenated in reverse order, or the data is striped or some other ROM needs to be modified to access the data once consolidated.I think that's how it works.
If these were socketed ROMs I'd just experiment but where these are surface mount and I'm not the best at SMD soldering I'd rather not risk damaging the PCB by removing/replacing these ICs multiple times while I attempt to get the data correct.
