The following driver updates: [Brian Troha]
Corrected rom names for the Megastar & Supertouch 30
Added missing rom to Supertouch 30 and verified old bad_dumps
Added documentation about the Megastar sets
Made pbst30b a clone of pbst30 and added program versions to the name, IE: Pit Boss Supertouch 30 (9234-10-01)
New Clone Added
-------------------------
Pit Boss Megastar (9244-00-01) [Brian Troha, Dumping Union]
Introduced DISCRETE_TASK_START, DISCRETE_TASK_END
DISCRETE_TASK_START
- Start a new task. A task is a set of nodes which only depend on input nodes and nodes in the set
DISCRETE_TASK_END(task_output_node)
- Marks the end of the task. task_output_node is the node whose output over time should be preserved. This node can be accessed by nodes in the main thread.
Order of execution:
a) All tasks in parallel
b) All nodes not part of a task. These may only refer to nodes listed in DISCRETE_TASK_END
Illustrated the concept in the dkong discrete emulation. This also has been enhanced to buffer DAC output.
Further changes:
- DISCRETE_OUTPUT now is a stepping node.
- DISCRETE_STREAM_INPUT now advances input pointer in step.
- More linked_list usage.
I estimate that the rework without tasks leads to a 5% performance gain. For dkong, the usage of tasks adds another 15%.
There are some features missing:
- Multiple nodes in DISCRETE_TASK_END
- More task consistency checks
- Task identifiers for tasks

I don't know this z80 emulator well enough to look into his first two points. Juergen?
1/ In the cc_xy[] table which lists instructions with DD or FD prefixes, "illegal" combos are returning 4 cycles when they should return 4 + cc_op (the normal instruction being executed). Another way to handle this correctly is to call EXEC(z80,fd,xx) or EXEC(z80,dd,xx) instead of op_xx(z80) when such pair of opcode is detected, to be sure the correct amount of cycles is used.
2/ According to Sean Young, R register is NOT incremented when chaining multiple DD or FD prefixes: [...]
This one was already fixed, dunno when:
2/ In the cc_ed[] table, INI (ED A2) and IND (ED AA) should return 16 cycles, like other instructions from this group, not 12. This seems to be a typo error.
Not working (100% correctly) like all games in the Mega-Tech Mega-Play driver
New Game Added
-------------------------------------
Great Football [Kevin Eshbach, Charles MacDonald, Smitdogg, Dumping Union]
- change the way custom modules are handled
- updated drivers mario and dkong accordingly
- minor change to stream input handling
- no more linear lists for nodes. All node processing switched to linked lists.
- module step and reset now only get a node pointer passed
- Added discrete_info * pointer to node
- Only nodes with a step routine actually get processed.
- Fixed a bug: discrete logs did not work since some time
- preliminary parallel task constants; depending on results these may vanish again.
- Overall slight performance increase. dkong 940% to 960%, galaxian 740% to 790%
- implemented carts banking and multiple EEPROMs
- added "pen replacement" blit mode
- fixed palette size
New games added or promoted from NOT_WORKING status

* Fixed the tile size/decode for the first GFX bank.
* Added proper norautrh inputs, including the readout button.
* Added partial DIP switches to norautrh.
* Added more technical notes.
Also fix Mantis 03284.

Noraut Poker (NTX10A) [Roberto Fresca, Alan Griffin]
Noraut Joker Poker (V3.010a) [Roberto Fresca, Alan Griffin]
- added unidasm to the tools build
- split the disassemblers out of libcpu and into new libdasm
- ensured the disassembly entry points for all disassemblers are
in the source file for the disassembler (sometimes new generic
versions were created)
Still needs command line options and file loading, but the
fundamentals are present, and it links.
- added discrete sound to battle zone
- engine frequency (resistor R11) can be changed with slider
- discrete sound may be disabled by setting BZONE_DISCRETE to 0 in bzone.h
DISCRETE_RCDISC3
- added diode junction voltage
- junction voltage also indicates polarity
DISCRETE_OPAMP_FILTER
- added type DISC_OP_AMP_FILTER_IS_LOW_PASS_1M
- INP2 takes role of v_ref in this type
DISCRETE_OPAMP
- Fixed a bug (possible divide by 0)
DISCRETE_LFSR
- Fixed bug preventing output of shift reg to sub node 1

Changed to mono both Downtown and Caliber 50: these pcbs don't have a
stereo connector.
Regarding the conversion to mono, I would like to know if it's good to
lower the output of the channels to 0.50 if each channel was previously
1.0 in stereo.

- Use new dump for ic31/32, ROM board test passes now
- Add protection hookup for Marvel vs. Capcom 2, game is playable w/sound
I'm not removing GAME_NOT_WORKING because I don't trust the Naomi emulation
in general that much yet, although I was able to coin up and play (slowly ;-)
Dump is uploading.

Olivier, this one's all yours. It pretty much nukes the existing video h/w
emulation but maybe you'll have better luck with it on your rewrite.
New Clone Added

- added cycle tables and cleaned up source layout. This was done very carefully, it should be errorfree.
- removed HLT cycle eating (earlier, HLT after EI could theoretically fail)
- fixed parity flag on add/sub/cmp. Bug was caused by z80 overflow detection accidentally left in
- renamed temp register XX to official name WZ
- renamed flags from Z80 style S Z Y H X V N C to S Z X5 H X3 P V C, and fixed X5 / V flags where accidentally broken due to flag names confusion
- Fixed X/Y flags in CCF/SCF/BIT, ZEXALL is happy now
- Simplified DAA, renamed MEMPTR (3.8) to WZ (same temp register as the officially named WZ in the 8080), added TODO
the cycle fix by Marshmellow, in the 3.9 z80.c comments was already committed in june, just added there for documentation
integers. This is defined to be "I64" on MSVC and recent mingw compilers,
and "ll" for all others.
Updated all instances of 64-bit prints to use the new macro.
Fixed visible area on logic pro and logic pro 2 to match real PCBs.
Add comment about what ym3812 clone is used.
Add note about missing graphical effect in logic pro (screen dim on coin insert) and marked as IMPERFECT_GRAPHICS.
Add note about 4 pixels at left edge of screen.

- Added Rabbit Poker / Arizona Poker? set (with GAL22V10 and PIC16F84A).
- Added proper decryption algorithms.
- Updated technical notes.

Rabbit Poker (Arizona Poker v1.1?) [Roberto Fresca, Andreas Naive, Tomasz Slanina]
- Put some life into RCDISC5 enable mode. This now acts as a switch between R and C. Capacitor voltage will be preserved if disabled.
- Made galaxian use the above. Saved 2 nodes and increased accuracy.
- Added DISC_LFSR_FLAG_OUTPUT_SR_SN1 flag to shift register noise generator. This will output the value of the shift register to sub-node 1. This is needed for future bzone discrete sound emulation. BTW: RCDISC5 will be used as well.
- Left a note on RCDISC3 on what is needed to be implemented for bzone.
- Optimized the LFSR a bit. LFSRs running at high frequency (> sample_freq) should benefit.
Colorama is a standalone game driven for 1x VGA board plus a mechanical arm.

reverted names back to just "1" versus multi_fish.001. It was pointed out the actual rom labels read just "1"... though in Igrosoft's list of hashes the full "multi_fish.001" name is used.
Stripped out the "hack" comments per game in lieu of a single comment about the first set being the "official" has while the other sets may be hacks or alt regions version.
- Use DISCRETE_NOTE for pitch generation; it is more accurate (within the one ms where the pitch changes :-) ) and saves a node
- Use DISCRETE_BITS_DECODE and save 2 nodes.
updated rom name based on listed files and hashes listed by Igrosoft. Added additional info about rom changes and found a bad_dump rom so 1 set gets removed.
