The CIC chip is not an EPROM, it's a custom gate layout, so you can't just grab an EPROM and program it. If you knew the gate layout you could potentially use something like a PAL or a GAL chip to program it but the pinout would probably be different and then you'd have to rework the PCB to get it to work which I don't recommend. And, to my knowledge no one on the net today knows the design of the CIC chips. Bung and FFE obviously reverse engineered (or copied) it but they're not giving out that information.

So in light of that what I would recommend is that you either take the CIC out of your DX (if you can locate it in the DX) or buy a cheap US or SFC cart and pull the CIC out of that.
