* adds a model to calculate mixing of channels with different resistance loads.
* based on above, each channel may be assigned a different load in individual case
i.e. channels not tied together
* rewrote ay8910.c to make emulation simpler
* changed the config structure to include a flag field and output resistor loads.
* Updated all drivers affected.
* Added some "Todos" related to stuff I discovered when reading datasheets.
* Fixed a bug in disc_flt.c (konami filters)
galaxian.c:
* Fixed discrete sound and konami filter addressing
* Changed addressing of AY-3-8910 to be in line with schematics
gyruss.c:
* Added discrete sound for filtering ("konami"-style) and mixing.
Hello Aaron,
I have found few more things not ok in T11, this time I have fixed it myself.
1. HALT - should call interrupt vector
2. ILLEGAL - had PC=0 at the end which makes code not run fine
3. MARK - now it is implemented
Can you please check if your drivers are working fine with these cahanges.
After adjustments I have some things working finaly.
Please inform me,
Miodrag Milanovic
Subject: [patch] Fix 01711: connect4, mpu4met0, mpu4tst2, mpu4utst, bctvidbs: Using -CHEAT trigger causes a crash
Hi mamedev,
This patch fixes bug 01711. Given the location of the original assert
it is clear the original code wasn't quite right.

Subject: [patch] Fix 00149: No error report for invalid BIOS setting.
Hi mamedev,
This small patch makes specifying an invalid bios a fatalerror and
removes the need to expose system_bios to the drivers by reworking the
code in playch10.c to determine its bios more directly (in other
words, it removes an ugly hack). This should resolve bug 00149,
although I did not implement the popmessage as suggested.

Subject: [patch] Fix 01588 timecrsa, timecris: MAME simply quits after
pressing F3 in both sets, game cannot be runned
Hi mamedev,
This small patch fixes the crash in bug 01588 and seems to allow the
game to start in most cases. In some cases in my testing the board
failed startup tests, but that appears to be unrelated.

Attached is diff which makes Touchmaster games playable.
General changes:
- Added preliminary 68681 DUART (machine\68681.c)
- Moved Microtouch touch screen controller emulation to separate module (machine\microtch.c)

Subject: Rygar third set dump
I named this dump as set 2 since it's the bugfix version like set 1. Set
3 was renamed old version because it has some bad bugs.
I haven't seen any visible differences, it would be interesting to see
what has changed in the program and if it's a newer revision than the
set 1 in mame...
New clones added:
Rygar (US set 3 Old Version)
that forcibly kills the application after a certain number of seconds.
Primarily intended to be used in regression test runs to handle the
occasional hung game.
- iqblocka: bypassed the protection, emulated the video hardware, inputs and sound.
- tjsb: it now boots and has partially decrypted graphics.
[Luca Elia]
Funworld updates:
- Removed the temporary hack to jolyc980.
- Updated technical notes regarding Magic Card II & Jolly Card Professional 2.0.
- Moved snookr10 to its own driver.
- Minor clean-up.

there are some issues, the unused palette bits are significant as the colours are wrong at the moment, also maybe it should be joystick, not spinner etc.. It's an ugly Korean hack game ;-)

Jumping Pop (NICs, Korean bootleg of Plump Pop) [Robin Cooper, David Haywood]
increased Varth CPU clock to 12MHz to reduce slowdowns (the game was released after sf2ce so the faster A-board was available).
verified more gfx rom mappings against PAL dumps (thanks to Corrado Tomaselli).
verified memory maps using A-board PAL dumps (thanks to Charles McDonald).
separated the address ranges for CPS-A and CPS-B customs. This finally clarifies why some registers are fixed and some change with every game.
identified three new unknown registers in the CPS-B-21 custom. Their purpose is unknown.
all unhandled accesses to CPS-A/CPS-B registers will now be reported. There shouldn't be any left. Look out for "contact MAMDEV" popups.
cleaned memory maps. Moved forgotten worlds special input mmeory handlers to DRIVER_INIT.
moved extra input handlers to video/cps1.c since the extra connectors are on the C-board.
added sound to Final Crash.
direct byte, word, dword, and qword accessors for all bus sizes,
there are now masked word, dword, and qword accessors for all
bus sizes.
IMPORTANT: masks that are passed to the _masked_* functions are
NOT inverted. Although inverted masks are still passed to callback
functions, when you request a masked read or write the masks should
represent the bits you want.
Updated the various MIPS cores that use these functions to invert
their masks.
Added support in the T-11 core for an external vector via irq_callback.
Apparently the hardware actually did support this and it is necessary
for emulating the BK 0010/11 computer in MESS.
range to be RAM-like for reads but calls the given handler for writes.
Replaced AM_READWRITE(SMH_RAM, handler) with AM_RAM_WRITE(handler).
Also replaced AM_RAM AM_WRITE(handler) with AM_RAM_WRITE(handler).
