Hello, I am working on testing a few memory chips I pulled from an NES game. The two chips were a 32K and a 128K EPROM. I have the CRC32 for the chips so I know what should be on them. I was able to read the 32K chip because its pinout is identical to a 27c256, and the checksum matched. For the 128K eprom, its pin out is not identical to another existing eprom. I think I may need to create a custom device for it to read correctly. Can anybody give me a hand?
