/*
** History:
**
** 2006-2008 Eke-Eke (Genesis Plus GX), MAME backport by R. Belmont.
**  - implemented PG overflow, aka "detune bug" (Ariel, Comix Zone, Shaq Fu, Spiderman,...), credits to Nemesis
**  - fixed SSG-EG support, credits to Nemesis and additional fixes from Alone Coder
**  - modified EG rates and frequency, tested by Nemesis on real hardware
**  - implemented LFO phase update for CH3 special mode (Warlock birds, Alladin bug sound)
**  - fixed Attack Rate update (Batman & Robin intro)
**  - fixed attenuation level at the start of Substain (Gynoug explosions)
**  - fixed EG decay->substain transition to handle special cases, like SL=0 and Decay rate is very slow (Mega Turrican tracks 03,09...)
**
** 06-23-2007 Zsolt Vasvari:
**  - changed the timing not to require the use of floating point calculations
**
** 03-08-2003 Jarek Burczynski:
**  - fixed YM2608 initial values (after the reset)
**  - fixed flag and irqmask handling (YM2608)
**  - fixed BUFRDY flag handling (YM2608)
**
** 14-06-2003 Jarek Burczynski:
**  - implemented all of the YM2608 status register flags
**  - implemented support for external memory read/write via YM2608
**  - implemented support for deltat memory limit register in YM2608 emulation
**
** 22-05-2003 Jarek Burczynski:
**  - fixed LFO PM calculations (copy&paste bugfix)
**
** 08-05-2003 Jarek Burczynski:
**  - fixed SSG support
**
** 22-04-2003 Jarek Burczynski:
**  - implemented 100% correct LFO generator (verified on real YM2610 and YM2608)
**
** 15-04-2003 Jarek Burczynski:
**  - added support for YM2608's register 0x110 - status mask
**
** 01-12-2002 Jarek Burczynski:
**  - fixed register addressing in YM2608, YM2610, YM2610B chips. (verified on real YM2608)
**    The addressing patch used for early Neo-Geo games can be removed now.
**
** 26-11-2002 Jarek Burczynski, Nicola Salmoria:
**  - recreated YM2608 ADPCM ROM using data from real YM2608's output which leads to:
**  - added emulation of YM2608 drums.
**  - output of YM2608 is two times lower now - same as YM2610 (verified on real YM2608)
**
** 16-08-2002 Jarek Burczynski:
**  - binary exact Envelope Generator (verified on real YM2203);
**    identical to YM2151
**  - corrected 'off by one' error in feedback calculations (when feedback is off)
**  - corrected connection (algorithm) calculation (verified on real YM2203 and YM2610)
**
** 18-12-2001 Jarek Burczynski:
**  - added SSG-EG support (verified on real YM2203)
**
** 12-08-2001 Jarek Burczynski:
**  - corrected sin_tab and tl_tab data (verified on real chip)
**  - corrected feedback calculations (verified on real chip)
**  - corrected phase generator calculations (verified on real chip)
**  - corrected envelope generator calculations (verified on real chip)
**  - corrected FM volume level (YM2610 and YM2610B).
**  - changed YMxxxUpdateOne() functions (YM2203, YM2608, YM2610, YM2610B, YM2612) :
**    this was needed to calculate YM2610 FM channels output correctly.
**    (Each FM channel is calculated as in other chips, but the output of the channel
**    gets shifted right by one *before* sending to accumulator. That was impossible to do
**    with previous implementation).
**
** 23-07-2001 Jarek Burczynski, Nicola Salmoria:
**  - corrected YM2610 ADPCM type A algorithm and tables (verified on real chip)
**
** 11-06-2001 Jarek Burczynski:
**  - corrected end of sample bug in ADPCMA_calc_cha().
**    Real YM2610 checks for equality between current and end addresses (only 20 LSB bits).
**
** 08-12-98 hiro-shi:
** rename ADPCMA -> ADPCMB, ADPCMB -> ADPCMA
** move ROM limit check.(CALC_CH? -> 2610Write1/2)
** test program (ADPCMB_TEST)
** move ADPCM A/B end check.
** ADPCMB repeat flag(no check)
** change ADPCM volume rate (8->16) (32->48).
**
** 09-12-98 hiro-shi:
** change ADPCM volume. (8->16, 48->64)
** replace ym2610 ch0/3 (YM-2610B)
** change ADPCM_SHIFT (10->8) missing bank change 0x4000-0xffff.
** add ADPCM_SHIFT_MASK
** change ADPCMA_DECODE_MIN/MAX.

		1 1 1 0  /\/\

		1 1 1 1  /___


		E = SSG-EG enable


		The shapes are generated using Attack, Decay and Sustain phases.

		Each single character in the diagrams above represents this whole
		sequence:

		- when KEY-ON = 1, normal Attack phase is generated (*without* any
		  difference when compared to normal mode),

		- later, when envelope level reaches minimum level (max volume),
		  the EG switches to Decay phase (which works with bigger steps
		  when compared to normal mode - see below),

		- later when envelope level passes the SL level,
		  the EG swithes to Sustain phase (which works with bigger steps
		  when compared to normal mode - see below),

		- finally when envelope level reaches maximum level (min volume),
		  the EG switches to Attack phase again (depends on actual waveform).

		Important is that when switch to Attack phase occurs, the phase counter
		of that operator will be zeroed-out (as in normal KEY-ON) but not always.
		(I havent found the rule for that - perhaps only when the output level is low)

		The difference (when compared to normal Envelope Generator mode) is
		that the resolution in Decay and Sustain phases is 4 times lower;
		this results in only 256 steps instead of normal 1024.
		In other words:
		when SSG-EG is disabled, the step inside of the EG is one,
		when SSG-EG is enabled, the step is four (in Decay and Sustain phases).

		Times between the level changes are the same in both modes.


		Important:
		Decay 1 Level (so called SL) is compared to actual SSG-EG output, so
		it is the same in both SSG and no-SSG modes, with this exception:

		when the SSG-EG is enabled and is generating raising levels
		(when the EG output is inverted) the SL will be found at wrong level !!!
		For example, when SL=02:
			0 -6 = -6dB in non-inverted EG output
			96-6 = -90dB in inverted EG output
		Which means that EG compares its level to SL as usual, and that the
		output is simply inverted afterall.


		The Yamaha's manuals say that AR should be set to 0x1f (max speed).
		That is not necessary, but then EG will be generating Attack phase.
