Reading the ROMs on my Marble Madness cart. Majority are masked ROMs and a few AMD EPROMs. The 16Kbyte read just fine.
The two masked ROMs that are 32Kbyte (201_E13 AND 202_D13) will not read as generic 27256 or 27C256. I can read the first half of them if I read them as 27128s.
Any ideas? I have no desire to drag out my Data I/O this evening!
