/* Hyper NeoGeo 64

Driver by David Haywood, ElSemi, and Andrew Gardner.
Rasterizing code provided in part by Andrew Zaferakis.

Notes:
  * The top board is likely identical for all revisions and all "versions" of the hardware.
    It contains the main MIPS CPU and a secondary communications KL5C80.
  * The bottom board is what changes between hardware "versions".  It has a Toshiba MCU with
    a protected internal ROM.  This MCU controls (at least) the inputs per game and communicates
    with the main board through dualport RAM.
  * I believe that this secondary board is used as a protection device.
    The "board type" code comes from it in dualport RAM, and each game reads its inputs differently through dualport.
    It's capable of changing the input ports dynamically (maybe explaining Roads Edge's "do not touch" quote below).
    It probably has a lot to do with the network (Roads Edge network connectors are on this board).
    And since it can return any value at any time, it may be responsible for fatfurwa's missing palette.
  * The Toshiba CPU datasheet is here : http://www.semicon.toshiba.co.jp/openb2b/websearch/productDetails.jsp?partKey=TMP87CH40N
  * The internal ROM needs dumping.  Rumor has it, it's the same MCU as in Naomi hardware...

  * From the Roads Edge manual : "The Network Check screen will be displayed for about 40 seconds whether
                                  the cabinet is connected for communication competition or not.  After this,
                                  the game screen will then appear.  At the same time the Network Check screen
                                  is displayed, the steering wheel will automatically straighten itself out."
                                 "During the Network Check, absolutely do not touch or try to use the steering wheel,
                                  pedal, shift lever, and switches.  This will cause the cabinet to malfunction."

  * The Japanese text on the Roads Edge network screen says : "waiting to connect network... please wait without touching machine"

ToDo:
  * clean up I/O / MCU communication
  * work out the purpose of the interrupts and how many are needed
  * correct game speed (seems too fast)
  * figure out what 'network' Road Edge needs to boot, it should run as a standalone
  * make ss64 boot (io return 3 then 4 not just 4) then work out where the palette is

  2d:
  * scroll (base registers?)
  * roz (4th tilemap in fatal fury should be floor [in progress], background should zoom)
  * find registers to control tilemap mode (4bpp/8bpp, 8x8, 16x16)
  * fix zooming sprites (zoom registers not understood, center versus edge pivot)
  * priorities
  * still some bad sprites/tiles (waterfall level 'splash' - health bar at 50% - intro top and bottom - fatfurwa test mode)
  * is all the bitmap decoding right?
  * upgrade to modern video timing.

  3d:
  * Find where the remainder of the 3d display list information is 'hiding' (FIFO?)
  * Remaining 3d bits - glowing, etc.
  * Populate the display buffers
  * Does the hng64 do perspective-correct texture mapping?  Doesn't look like it...

  Other:
  * Translate KL5C80 docs and finish up the implementation
  * figure out what IO $54 & $72 are on the communications CPU
  * hook up CPU2 (v30 based?) no rom? (maybe its the 'sound driver' the game uploads?)
  * add sound
  * backup ram etc.
  * correct cpu speed and find idle skips
  * What is ROM1?  Data for the KL5C80?  There's plenty of physical space to map it to.

Notes:
       1. The game cart plugs into the main PCB on the TOP side into CONN9 & CONN10
       2. If the game cart is not plugged in, the hardware shows nothing on screen.




Hyper Neo Geo game cartridges
-----------------------------

The game carts contains nothing except a huge pile of surface mounted ROMs
on both sides of the PCB. On a DG1 cart all the roms are 32Mbits, for the
DG2 cart the SC and SP roms are 64Mbit.
The DG1 cart can accept a maximum of 96 ROMs
The DG2 cart can accept a maximum of 84 ROMs


The actual carts are mostly only about 1/3rd to 1/2 populated.
Some of the IC locations between DG1 and DG2 are different also. See the source code below
for the exact number of ROMs used per game and ROM placements.

Games that use the LVS-DG1 cart: Road's Edge

Games that use the LVS-DG2 cart: Fatal Fury: Wild Ambition, Buriki One, SS 64 II

Other games not dumped yet     : Samurai Spirits 64 / Samurai Shodown 64
                                 Samurai Spirits II: Asura Zanmaden / Samurai Shodown: Warrior's Rage
                                 Off Beat Racer / Xtreme Rally

                               * Different regions might use the same roms, not known yet

 Notes:
      Not all ROM positions are populated, check the source for exact ROM usage.
      ROMs are mirrored. i.e. TX/PR/SP/SC etc ROMs line up on both sides of the PCB.
      There are 4 copies of each TX ROM on the PCB.

info from Daemon

(MACHINE CODE ERROR):
Is given when you try to put a "RACING GAME" on a "FIGHTING" board.

There are various types of neogeo64 boards:
FIGHTING (revision 1 and 2)
RACING
SHOOTING
and
SAMURAI SHODOWN ONLY (Korean)

FIGHTING boards will ONLY play fighting games.

RACING boards will ONLY play racing games (and you need the extra gimmicks
to connect analog wheel and pedals, otherwise it gives you yet another
error).

Shooter boards will only work with Beast Busters 2.

And the Korean board only plays Samurai Shodown games (wont play Buriki One
or Fatal Fury for example).
