/***********************************************************************************************************
  Barcrest MPU4 highly preliminary driver by J.Wallace, and Anonymous.

  This is the core driver, no video specific stuff should go in here.
  This driver holds all the mechanical games.

     05-2009: Miscellaneous lamp fixes, based on data from FME Forever.
     09-2007: Haze: Added Deal 'Em video support.
  03-08-2007: J Wallace: Removed audio filter for now, since sound is more accurate without them.
                         Connect 4 now has the right sound.
  03-07-2007: J Wallace: Several major changes, including input relabelling, and system timer improvements.
     06-2007: Atari Ace, many cleanups and optimizations of I/O routines
  09-06-2007: J Wallace: Fixed 50Hz detection circuit.
  09-04-2007: J Wallace: Corrected a lot of out of date info in this revision history.
                         Revisionism, if you will.
  17-02-2007: J Wallace: Added Deal 'Em - still needs some work.
  10-02-2007: J Wallace: Improved input timing.
  30-01-2007: J Wallace: Characteriser rewritten to run the 'extra' data needed by some games.
  24-01-2007: J Wallace: With thanks to Canonman and HIGHWAYMAN/System 80, I was able to confirm a seemingly
              ghastly misuse of a PIA is actually on the real hardware. This fixes the meters.
  30-12-2006: J Wallace: Fixed init routines, state saving is theoretically supported.
  23-09-2006: Converted 7Segment code to cleaner version, but have yet to add new 16k EPROM, as
              the original image was purported to come from a Barcrest BBS service, and is probably
              more 'official'.
  07-09-2006: It appears that the video firmware is intended to be a 16k EPROM, not 64k as dumped.
              In fact, the current dump is just the code repeated 4 times, when nothing earlier than
              0xC000 is ever called. Presumably, the ROM is loaded into C000, and the remainder of the
              'ROM' space is in fact the extra 32k of RAM apparently needed to hold the video board data.
              For now, we'll continue to use the old dump, as I am unsure as to how to map this in MAME.
              Changed Turn Over's name, it's either 12 Pound or 20 Pound Turn Over, depending on settings.

              At this stage, I cannot see how to progress any further with the emulation, so I have transferred
              a non-AWP version of this driver to MAME for further study.

  06-09-2006: Connect 4 added - VFD is currently reversed, although it looks to me like
              that's the correct behaviour, and that my 'correction' for Old Timer was wrong.
              AY sound does work, but is horrendous - presumably there's a filter on the
              sound that I haven't spotted. Trackball is apparently connected to AUX1, via
              Schmitt triggers - I wish I had a clue what this meant (El Condor).

  05-09-2006: And the award for most bone-headed bug goes to.. me! the 6840 handler wasn't
              resetting the clocks after timeout, so the wave frequencies were way off.
              Machines now hang on reset due to a lack of reel support.
              CHR decoding now included, but still requires knowledge of the data table
              location - this should be present in the ROMs somewhere.

  11-08-2006: It appears that the PIA IRQ's are not connected after all - but even
              disabling these won't get around the PTM issues.
              It also looks like the video card CHR is just a word-based version
              of the original, byte-based chip, meaning that should be fairly simple
              to emulate too, when the time comes.

  08-07-2006: Revised mapping of peripherals, and found method of calculating CHR
              values - although their use is still unknown.

  11-05-2006: El Condor, working from schematics and photos at present
  28-04-2006: El Condor
  20-05-2004: Re-Animator

--- Board Setup ---

The MPU4 BOARD is the driver board, originally designed to run Fruit Machines made by the Barcrest Group, but later
licensed to other firms as a general purpose unit (even some old Photo-Me booths used the unit).

This original board uses a ~1.72 Mhz 6809B CPU, and a number of PIA6821 chips for multiplexing inputs and the like.

A 6840PTM is used for internal timing, one of it's functions is to act with an AY8913 chip as a crude analogue sound device.
(Data is transmitted through a PIA, with a square wave from the PTM being used as the alarm sound generator)

A MPU4 GAME CARD (cartridge) plugs into the MPU4 board containing the game, and a protection PAL (the 'characteriser').
This PAL, as well as protecting the games, also controlled some of the lamp address matrix for many games, and acted as
an anti-tampering device which helped to prevent the hacking of certain titles in a manner which broke UK gaming laws.

One of the advantages of the hardware setup was that the developer could change the nature of the game card
up to a point, adding extra lamp support, different amounts of RAM, and (in many cases) an OKI MSM6376 or Yamaha synth chip
and related PIA and PTM for improved audio (This was eventually made the only way to generate sound in MOD4 of the hardware,
when the AY8913 was removed from the main board)

Everything here is preliminary...  the boards are quite fussy with regards their self tests
and the timing may have to be perfect for them to function correctly.  (as the comms are
timer driven, the video is capable of various raster effects etc.)

Datasheets are available for the main components, The AGEMAME site mirrors a few of the harder-to-find ones.

/*
Characteriser (CHR)

I haven't been able to work out all the ways of finding the CHR data, but there must be a flag in the ROMs
somewhere to pick it out. As built, the CHR is a PAL which can perform basic bit manipulation according to an as yet unknown unique key. However, the programmers decided to best use this protection device in read/write/compare
cycles, storing almost the entire 'hidden' data table in the ROMs in plain sight. Only later rebuilds by BwB
avoided this 'feature' of the development kit, and as such, only low level access can defeat their protection.

This information has been used to generate the CHR tables loaded by the programs, until a key can be determined.

For most Barcrest games, the following method was used:

To calculate the values necessary to program the CHR, we must first find the version string, taking
the example of an AWP called Club Celebration, this starts at 0xff28 and terminates at 0xff2f.
0xff2f then represents the CHR address.
For some reason, the tables always seem to start and end with '00 00'.

From that point on, every word represents a call and response pair, until we have generated 8 8 byte rows of data.

The call values appear to be fixed, so it would be possible to make a switch statement, but I believe the emulated
behaviour to be more likely.

The initial 'PALTEST' routine as found in the Barcrest programs simply writes the first 'call' to the CHR space,
to read back the 'response'. There is no attempt to alter the order or anything else, just
a simple runthrough of the entire data table. The only 'catch' in this is to note that the CHR chip always scans
through the table starting at the last accessed data value, unless 00 is used to reset to the beginning.

However, a final 8 byte row, that controls the lamp matrix is not tested - to date, no-one outside of Barcrest knows
how this is generated, and currently trial and error is the only sensible method. It is noted that the default,
of all 00, is sometimes the correct answer, particularly in non-Barcrest use of the CHR chip, though when used normally,
there are again fixed call values.
