Namco early 8080-based games

All these games run on the same hardware design, with minor differences.

Gee Bee was the very first videogame released by Namco, and runs on a b&w board.
The year after, the design was upgraded to add color and a second sound channel;
however, the b&w board was not abandoned, and more games were written for it with
the only difference of a larger gfx ROM (losing the ability to choose full or half
brightness for each character).

Notes:
- Warp Warp Easter egg:
  - enter service mode
  - keep B1 pressed and enter the following sequence:
    2xR 6xD L 4xU
  (c) 1981 NAMCO LTD. will be added at the bottom of the screen.

- In the pinball games, there isn't a player 2 "serve" button - both players use
  the same input. I think this is correct behaviour, because there is nothing in
  the schematics suggesting otherwise (while there is a provision to switch from
  one paddle to the other). The Bomb Bee flyer shows that the cocktail cabinet
  did have one serve button per player, but I guess they were just wired together
  on the same input.

- The ball size changes from game to game. I have determined what I believe are
  the correct sizes by checking how the games handle the ball position in
  cocktail mode (the ball isn't automatically flipped by the hardware).

- kaitei and kaiteik are intriguing. The game is more or less the same, but the
  code is radically different, and the gfx ROMs are arranged differently.
  kaitei is by Namco and kaiteik is by "K'K-TOKKI". kaitei does a ROM/RAM
  test on startup, while kaiteik jumps straight into the game. kaitei is
  locked in cocktail mode, while kaiteik has support for a cabinet dip
  switch. The title screen in kaitei is nice and polished, while in kaiteik
  it's confused, with fishes going over the text. There are several other
  differences.
  The code in kaiteik is longer (0x1800 bytes vs. just 0x1000 in kaitei) and
  less efficient, while kaitei has some clever space optimizations.
  My opinion is that kaiteik is the prototype version, developed by a third
  party and sold to Namco, where it was rewritten.

- The coin counter doesn't work in kaiteik. This might be the expected behaviour.

- sos does a "coffee break" every 2000 points, showing a girl. The first times,
  she wears a bikini. If the "nudity" switch is on, after 6000 points she's
  topless and every 10000 points she's nude.

- The only difference between 'warpwarr' and 'warpwar2' is the copyright
  string on the first screen (when the scores are displayed) :
  * 'warpwarr' : "(c) 1981 ROCK-OLA MFG.CORP."  (text stored at 0x33ff to 0x3417)
  * 'warpwar2' : "(c) 1981 ROCK-OLA MFG.CO."    (text stored at 0x33ff to 0x3415)
  Note that the checksum at 0x37ff (used for checking ROM at 0x3000 to 0x37ff)
  is different of course.

- warpwarr doesn't have an explicit Namco copyright notice, but in the default
  high score table the names are NNN AAA MMM CCC OOO. warpwarp doesn't have an
  high score table at all.


TODO:
- I arbitrarily assigned a uniform blue overlay to sos. I don't know how it's
  supposed to be. navarone and kaitei are missing the overlay too.
