Atomis Wave (system overview)
Sammy/SEGA, 2002

This is one of the latest arcade systems so far, basically just a Dreamcast using ROM carts.

                  This is a little strange, the ROM appears to be a standard SOP44 with reverse pinout but the
                  address lines are shifted one pin out of position compared to industry-standard pinouts.
                  The actual part number doesn't exist on the Macronix web site, even though they have datasheets for
                  everything else! So it's probably a custom design for Sammy and top-secret!
                  The size is assumed to be 1MBit and is 8-bit (D0-D7 only). The pinout appears to be this.....

Notes:
      Not all MASKROM positions are populated.
      All MASKROMs (IC1 to IC21) are SOP44, either 32M or 64M
      The other side of the cart PCB just has more locations for
      SOP44 MASKROMs... IC12 to IC21 (ROM12 to ROM21)

      IC22    - DIP42 EPROM, either 27C160 or 27C322
      JP1     - Sets the size of the EPROM. 1-2 = 32M, 2-3 = 16M
      IC41    - Xilinx XC9536 (PLCC44)
      IC42    - SEGA 315-5881 (QFP100). Probably some kind of FPGA or CPLD. Usually different per game.
                On the end of the number, -JPN means it requires Japanese BIOS, -COM will run with any BIOS
      X76F100 - Xicor X76F100 secured EEPROM (SOIC8)
      71256   - IDT 71256 32kx8 SRAM (SOJ28)
      CN1/2/3 - connectors joining to main board

      Note! Generally, games that require a special I/O board or controller will not boot at all with a
            standard NAOMI I/O board. Usually they display a message saying the I/O board is not acceptable
            or not connected properly.

        IC18 - Fujitsu 29DL640E 64M TSOP48 FlashROM. This ROM has no additional custom markings
               The name in the archive has been devised purely for convenience.
               This ROM holds the main program.

IC10 to IC17 - Custom-badged 128M TSOP48 maskROMs. I suspect they are Macronix
               ROMs because the ROM on the main board is also a custom Macronix
               ROM and they have a history of producing custom ROMs for other
               companies that hide their ROM types like Nintendo etc.
               The ROMs match a pinout that is identical to....
               Macronix MX26F128J3 (TSOP48)
               Oki MR27V12800 (TSOP48)
               More importantly the size is standard TSOP48 20mm long.
               They have been read as Oki MR27V12800
               The pinout also matches the same ROMs found on Namco Mr Driller 2
               and some Namco and Capcom NAOMI carts where these ROMs are used,
               although in all cases those ROMs are 18mm long, not 20mm.

EPR-23608B - NAOMI BOOT ROM 2001 09/10  1.70 (Export)

EPR-23605B, EPR-23607B & EPR-23608B all differ by 8 bytes:

0x0553a0 is the first region byte
0x1ecf40 is a second region byte (value is the same as the first region byte )
0x1fffa-1ffff is the BIOS rom checksum

Region byte encoding is as follows:

0x00 = Japan
0x01 = USA
0x02 = Export
0x?? = Korea
0x?? = Australia

default session key is
"NAOMIGDROMSYSTEM"

info from Elsemi:

it sends bsec_ver, and if it's ok, then the next commands are the session key changes
if you want to have the encryption described somewhere so it's not lost. it's simple:
unsigned char Enc(unsigned char val,unsigned char n)
{
    val^=Key[8+n];
    val+=Key[n];

    return val;
}

do for each value in the message to send
that will encrypt the char in the nth position in the packet to send
time to go to sleep
