I was thinking I could maybe take the RXD and RTS from either device and wire into the computer while the 2 devices are communicating to intercept the communication one way.
#NAOMI EMULATOR CONTROL SETUP SERIAL#
I've got a working serial port on an older laptop that I was hoping to use in the initial experiments before moving to an RPi. I would initially appreciate any help with regards to methods I could use for sniffing the signals and help addressing any concerns over signal voltage differences between computer and NAOMI 2. I've got almost no experience with serial communication standards.

After that, it's a matter of figuring out what communication happens back and forth during the reading and writing of the card, then somehow figuring out how to store that data and give it back to the NAOMI when it expects it. The short term goal would be to trick the NAOMI into thinking the card reader has initialized. After getting that information, I could try to unhook the reader and wire up just the computer to send the same signals back to the NAOMI2 that it expects from the reader. My thinking is that while the 2 are wired up, I could tap into one side of this communication and sniff it with a serial input on the computer to read what's happening one way and then wire in to the other and see what's happening in that direction. In my brief review of serial communication standards, I believe that in spite of the CN8 port on NAOMI 2 saying RS-422, the labeling of the pins for the card reader make me think the standard is RS-232. The data is transmitted between the NAOMI and Card Reader by serial communication. Apparently cards are getting hard to come by, too, and each has a limit of 50 uses as far as I know. If that works, then others can get a cheap alternative to the expensive and dying card readers. While I'm good to go with a currently working setup and a large quantity of compatible cards, I thought it would be a fun project to try to emulate the card reader, maybe using a Raspberry Pi, so that the NAOMI thinks a card reader is plugged up, and the data can be saved and loaded accordingly. For this game, the cards work essentially to save your progress along with car upgrades. I've also got an ID3 card reader and cards, and have that wired up and working just fine. I've got a Sega driving cab (OutRun2 SP) and I've got a NAOMI 2 hooked up and netbooting working. I had brought up this idea on KLOV and someone suggested I might get more interest/feedback/help here, so here goes!Įmulate the NAOMI 2 card reader and interface it with an actual NAOMI 2 for the purposes of saving progress in Initial D3.
