Several Namco games from 1982-1985

driver by Nicola Salmoria
based on previous work by Aaron Giles, Manuel Abadia

The games supported by this driver all run on similar hardware.
They can be divided in three "families":
1) Super Pacman, the first version of the board. Pac & Pal and Grobda run on
   seemingly identical hardware.
   The hardware consists of two 6809, and several Namco custom ICs that provide
   a static tilemap and 2bpp sprites.
   Grobda is the only Namco game of this era that has speech (just a short
   sample). At this time, it is still unknown whether the DAC used to play
   the speech is part of the standard Namco sound hardware, or a quick addition
   to the base board.
2) Phozon. This game runs on an unique board: the large number of sprites on
   screen at the same time required a 3rd 6809 to help with the calculations.
   The sprite hardware is also different from Super Pacman, featuring 8x8 sprites.
   Despite the hardware differences, the memory map is almost identical to
   Super Pacman, and that's why it's included in this driver.
   There is no information about the custom ICs used by this board. The video
   section is probably more similar to Gaplus than to Supr Pacman: the sprite
   generator might be a 21XX (though Gaplus doesn't use 8x8 sprites), and the
   00XX and 04XX address generators are probably replaced by the single CUS20
   (which also handles the flip screen flag).
3) Mappy runs on a revised design of the Super Pacman board, where the 00XX
   custom is replaced by a 17XX, which provides a scrolling tilemap. The larger
   tilemap requires more RAM, so the memory map is slightly different. Also,
   sprites are 4bpp instead of 2bpp, so the final stage of video generation is
   a little different as well, though the custom ICs are still the same.
   Dig Dig II and Motos are almost the same, apart from larger ROMs.
   The Tower of Druaga also has 4x the amount of sprite color combinations so
   it's the most different of the four.


Custom ICs (Super Pacman and Mappy):
-----------------------------------
CPU board:
07XX     clock divider
15XX     sound control
16XX     I/O control
5xXX(x2) I/O
99XX     sound volume (only Mappy, Super Pacman uses a standard LS273)

Video board:
00XX     tilemap address generator with scrolling capability (only Super Pacman)
04XX     sprite address generator
07XX     clock divider
11XX     gfx data shifter and mixer (16-bit in, 4-bit out) [1]
12XX     sprite generator
17XX     tilemap address generator with scrolling capability (only Mappy)

[1] Used differently: in Super Pacman it merges the 2bpp tilemap with the 2bpp
sprites; in Mappy it handles the 4bpp sprites, while the tilemap is handled by
standard LS components.

The I/O interface chips vary from game to game (see machine/namcoio.c)


Super Pac-Man memory map
------------------------
Pac & Pal is the same. Grobda appears to have a DAC hacked in.
Note: Part of the address decoding is done by PALs (SPC-5 and SPC-6) so the
tables are inferred by program behaviour.

Mappy memory map
----------------
The Tower of Druaga, Dig Dug 2, Motos are the same, with minor differences.
The main difference with Super Pac-Man is the increased video RAM, needed to
implement a scrolling tilemap.

Note: Part of the address decoding is done by PALs (SPC-5 and SPC-6, the same
as Super Pac-Man) so the tables are inferred by program behaviour.

Notes:
-----
- Phozon: completing level 34 (the second round of world 9) causes the game to
  crash. This seems to be the correct behaviour: there is no data for levels
  after that one, and using the level select dip switch to jump to level 35
  (="22") causes the same crash. I think being able to complete level 34 is a
  bug, it should be impossible because there shouldn't be enough molecules so
  you would play it forever.

- Phozon: if you enter service mode and press service coin something
  like the following is written at the bottom of the screen:
  99,99999,9999,9999,9999
  99,99999,9999,9999,999999
  it seems to be a counter decremented while the game is running.

- Mappy: similarly, if you enter service mode and press press
  P1 button + service coin the following is shown:
  99.99.999.9999.9999.9999
  99.99.999.9999.9999.0000

- The Tower of Druaga: keep button 1 pressed while pressing the start button to
  continue the previous game; you can choose which level to start from.

- Grobda: when the Level Select dip switch is On, after inserting a coin press
  button + start to be asked the level to start from.

- The only difference between "grobda2" and "grobda3" is a tiny patch to some
  code related to player shoots handling. Bugfix, I guess.

- Dig Dug II: when the "freeze" dip switch is on, at the beginning of the game
  select starting level with joystick up/down, then press button 2. During the
  game, press start to pause/resume.


TODO:
----

- Phozon: there appear to be two palette banks (sprites are the same, but
  characters change from a blue background to brown background). It is not
  known if and when the alternate palette should be used. The palette select
  bit might be at address 500E/500F; if that's the case, it is set to 0 on
  startup and I don't think it's ever set to 1 - which would mean the second
  bank is not used and colors are right as they are.

- Phozon: one unknown PROM, I don't know what it could be.
