The Konami Twinkle hardware basically consists of the following parts....
3 PCBs sandwiched together in a metal box
SCSI CDROM drive (for main program CD)
External DVD player (plays VCD)
CD disc (for main program)
Security dongle
IDE HDD (for audio)
VCD disc (for video)

The top board appears to be the main CPU/graphics board.
The middle board appears to be for the video output/overlay.
The bottom board appears to be for sound.

Notes:
      CN1        - 50 pin SCSI connector for CDROM drive

      CN8        - RJ45 network connector
      CN9        - 40 pin flat cable I/O connector
      CNx        - Security card connector. The security cart contains only
                   one IC, a ST 2402W 2kbit serial I2C bus EEPROM (TSSOP8)
                   It appears only the first 12 bytes are actually used in this chip. The earlier games
                   (possibly from BMIIDX 2nd Style and before) use a similar IC but it is not directly
                   readable like the 2402W. The chip is covered with epoxy so the actual type is unknown.
