/***************************************************************************
Namco NA-1 / NA-2 System

NA-1 Games:
-   Bakuretsu Quiz Ma-Q Dai Bouken
-   F/A / Fighter & Attacker
-   Super World Court (C354, C357)
-   Exvania (C350, C354)
-   Cosmo Gang the Puzzle (C356)
-   Tinkle Pit (C354, C367)
-   Emeraldia (C354, C358)

NA-2 Games:
-   Knuckle Heads
-   Numan Athletics
-   Emeraldia (C354, C358)
-   Nettou! Gekitou! Quiztou!! (C354, C365 - both are 32pin)
-   X-Day 2

To Do:
- Remove remaining MCU simulation hacks
- View area / screen resolution controlled by registers?

- X-Day 2:
    Rom board  M112
    Rom board custom Key chip i.d. C394
    Game uses a small cash-register type printer (connects to rom board)
    Game also has a large L.E.D. type score board with several
    displays for various scores. (connects to rom board)
    Game uses coin-type battery on rom board. (not suicide)
    Game won't startup unless printer is connected and with paper.

The board has a 28c16 EEPROM

No other CPUs on the board, but there are many custom chips.
Mother Board:
210 (28pin SOP)
C69 or C70 (80pin PQFP)
215 (176pin PQFP)
C218 (208pin PQFP)
219 (160pin PQFP)
Plus 1 or 2 custom chips on ROM board.

Notes:

-   NA-2 is backwards compatible with NA-1.

-   Some NA-1 PCBs are known to have the NA-2 (C70) MCU BIOS, so that cannot
    be used to tell them apart.

-   Test mode for NA2 games includes an additional item: UART Test.
    No games are known to actually link up and use the UART feature.
    It's been confirmed that a Numan Athletics fails the UART test,
    behaving as it does in MAME.

-   Quiz games use 1p button 1 to pick test, 2p button 1 to begin test,
    and 2p button 2 to exit. Because quiz games doesn't have joystick.

-   Almost all quiz games using JAMMA edge connector assign
    button1 to up, button 2 to down, button 3 to left, button 4 to right.
    But Taito F2 quiz games assign button 3 to right and button 4 to left.

-   Emeralda: Byte 0x25 of the NVRAM, when zero, enables the FBI logo.
