Announcing Sega's FD1094 Reverse Engineering


Dear all, it is my pleasure to announce the beginning of Sega's FD1094 reverse engineering effort. As it was with Kabuki, the main goal is to understand the programing secrets of this security processor featured in plenty of arcade games developed by Sega.

After having spent some time studying it, I firmly believe Sega's FD is probably one of the more complex and beautiful chips ever designed.

Stay tuned.

ps: If you hold a stash of FD1904 & FD1089 cpu's please consider donating any spare units to the cause, contributions welcome.

    Do you have any plans to take a look at the encrypted Z80 modules (NEC MC-8123B) like with the Kabuki previously as well?
    This chip is lurking on one of my Shinobi System16B boards. Would love to be able to throw in a fresh battery and rekey it. Cheers!
