Thanks a lot! I understand why wou don't want to crack them out - but it would be great if you could just remove the Rainbow's "baking tray" and take pictures of the mainboard and cards - this would allow us to crossreference your dump with the actual chip parts.
Another potential shortcoming of this method is that debug can't reach the chargen ROM and Z80 arbitation PROMs that are in MAME's ROM definition as well.
