And going by the data sheet, just a 64-bit PROM (one-time programmable read-only memory). Not an enigma like the CIC at all. :)

Wow, that would have been much easier to reverse engineer than the rabbit since we already know the hardware specs. All it would have taken is the die photo's to extract the binary, and a reverse assembler. Why didn't we think of that before?

Always possible the part number is fake, misinformation is always a good tactic :P

If it were a 64-bit PROM, you could just read its contents and burn that to a new PROM. No microscope necessary. :)

Looking at a MAME romset for a Playchoice 10 game, there is a file called security.prm which is labeled as being the RP5H01 data. Exactly what the data contains and is used for is unclear.

Looks like a new thread in the making, and requests for copyrighted files that might not be appropriate for Nesdev.

Tengen weren't the only ones to create their own CIC clone.
On Snes, Datel created the Action Replay.
I've opened mine (AR MK3), and tried to find where the CIC was.

The numbers are the cartidge connectors.
"Datel Turbo Replay" seems to be a multi-purpose chip, and the other chip is an eprom. Has anyone already decapped it, or is willing to do it? Maybe it would be easier to understand the algorithm...

Are you sure the Action Replay doesn't just use the plugin cart's CIC or does it contain both NTSC and PAL defeation?

Game Genie passes the CIC signals through to the Game Pak. I'm guessing that because a lot of unlicensed games do the same, Action Replay is likely to do so as well.

I know that the Bung SF7 didn't require a cart in the SNES to play games. Did it have a CIC clone in it?
Same for the SWC DX I have.

Yes, all game copiers apart from the Super Magicom and perhaps early Super UFOs have CIC clones in them.
