Version 0.88 "FD1094"

Released: 2004-10-24

General Improvements

• Emulation of Sega FD1094 encrypted 68k CPUs, this will allow for significant progress in the emulation of the remaining encrypted Sega games. Note that we require working CPUs to extract encryption data from in order to emulate the encrypted titles, see http://cgfm2.emuviews.com/ for more details. As a result of this code several of the encrypted games will now boot (astorm, ddcrew, wb3a, wb3b, tetris, ddux, sonicbom etc.)

[Charles MacDonald - extracting data from CPUs, Nicola Salmoria - decryption code]

• Misc fixes from Mame32Plus

• ay.diff: add save state support for AY8910 and friends
• crbaloon.diff: add music support
• darius.diff: adjust FM/ADPCM balance
• f3.diff: fix landmakr sound loading

• i960 and model 2 update [R.Belmont, ElSemi]

i960:

• Fixed bug in movl (ElSemi)

model2:

• Removed hotd and lastbrnx hacks, the i960 fix obsoletes them
• Added port 0 switching, player 2 start works in several games now (ElSemi)
• Added working timer support, including timer IRQs
• Updated game status listing

• Fixed some c99 related compiler issues [Jeff Mitchell, Lawrence Gold]

• update to ppmast93 driver, still not playable [David Haywood]

• Discrete sound changes [Derrick Renaud]

Discrete Sound Changes

• Continued cleanup of code to make it more readable

New Discrete Modules Added

• DISCRETE_NOTE - counter circuit used to create tones/music.
• DISCRETE_INTEGRATE - various op amp integration (ramp) circuits.
• DISCRETE_OP_AMP_TRIG_VCA - Did not know what to call this. :-) Basically it is a programable voltage controlled amp. But uses only an on/off trigger. It has resistors to select the rise/fall times. Also it is not a true VCA. It actually adjusts amplitude by clipping more/less off the bottom of the input signal. But it is a common circuit.

Game Driver Changes

• polaris - complete sound rewrite to use new component value code. Hooked up watchdog timer.

• New watchdog functionality [Derrick Renaud]

Game Driver Changes

• dominos, sprint1, sprint2, dragrace, canyon, nitedrvr - added watchdog and set to proper time using new MDRV_WATCHDOG_VBLANK_INIT function.
• firetrk, montecar, superbug, pacman, polaris - changed watchdog to proper time using new MDRV_WATCHDOG_VBLANK_INIT function.
• galpania, galpanib - changed to MDRV_WATCHDOG_VBLANK_INIT because these games need watchdog init at game start.

Core Changes

• Changed watchdog to allow it to start at machine run start. If not used, the previous watchdog functionality is retained. Only define 1 of the 2 watchdogs per game. If both are defined then MDRV_WATCHDOG_VBLANK_INIT will be used only.

• MDRV_WATCHDOG_VBLANK_INIT(watch_count)- Initializes the watchdog in MACHINE_DRIVER_. watch_count is the # of vertical blanking intervals before a forced reset. If the time is unkown then you can use these defaults: DEFAULT_60HZ_3S_VBLANK_WATCHDOG or DEFAULT_30HZ_3S_VBLANK_WATCHDOG

• MDRV_WATCHDOG_TIME_INIT(time)- Initializes the watchdog in MACHINE_DRIVER_. time is the time in seconds before a forced reset.

• New function to enable/disable the watchdog in game.

watchdog_enable(0 or 1) - used to 0=disable or !0=enable.

Made a macro that calculates the pulse time of a 74LS122 or LS123.

TIME_OF_74LS123(r,c)

r is in Ohms. c is in Farads.

c must be greater then 1000pF to use this function

• Added runtime option to disable validity checks [Derrick Renaud]

Added run time option:

-[no]skip_validitychecks

Forces MAME to skip doing the code validity checks. The default is OFF (-noskip_validitychecks).

This new option will default to doing the test and force you to confirm you do not want to use it. This way users can test their submissions easily and then speed things up when confirmed ok.

NOTE: DO NOT disable the checks when submitting code

• Fixed voodoo code broken by cleanup in u3 [Aaron Giles]

• Fixed qdrmfgp broken by cleanup in u3 [Olivier Galibert]

• Fixed cut and paste error in chdman [René Single]

• Fixed mayday inputs [Stefan Jokisch]

• Fixed Puzzle Club dips [Brian Troha]

• Input Port System Update [Aaron Giles]

PORT_INCLUDE() works the same as before.

PORT_MODIFY("tag") allows you to modify any given input port by specifying its tag.

Any PORT_BIT() entries that you put after a PORT_MODIFY will nuke any matching entries in the previous definition, allowing you to overwrite them with new stuff.

I also added a few new functions:

readinputportbytag_safe() takes a tag and a default value. If the tag is not found, the default value is returned.

port_tag_to_handler8()

port_tag_to_handler16()

port_tag_to_handler32() -- these 3 new functions take a tag string, find the input port, and return the appropriate handler. They can be used in AM_READ, so instead of:

AM_RANGE(0x00, 0x00) AM_READ(input_port_1_r)

You can use

AM_RANGE(0x00, 0x00) AM_READ(port_tag_to_handler8("MyPortName"))

I've modified exidy.c to use these features as a testbed. Let me know if you see any problems.

• Memory system changes / fixes [Aaron Giles]

• added explicit casting to the memory handler width when computing the shifted data/mask values for read/write handlers -- this should in theory fix R. Belmont's 64-bit issues

• added memory_install_read/write8/16/32/64_matchmask_handler functions to allow dynamic installation of match/mask (AM_SPACE-style) memory ranges -- this should satisfy Frank P's request for the astrocade driver

• changed masking behavior for match/mask pairs so that an AM_SPACE with an AM_MASK does not expand the explicitly-specified mask value -- this should fix dwidel's problem getting Pac-Man accurate

• changed dynamic bank assignment to always assign a bank if you have explicitly specified a mask value via AM_MASK -- this should allow mirroring via AM_MASK if you want to, though AM_MIRROR is still preferred

• Fixed OKI banking in Fixeight bootleg [Quench]

• More changes [Derrick Renaud]

Game Driver Changes

• firetrk, montecar - added proper CPU clock frequency change when going in/out of service mode.

Core Changes

• Fixed some last remaining issues with the new watchdog. The watchdog would not remain disabled after a watchdog_enable(0) in some conditions.

• Added a new function to change CPU clock speed in game. The current scaling factor will still apply. eg. If you force the CPU to change clock to 1MHz while the scaling is at 50%, the effective CPU speed will be 500kHz. Then reading the clock speed will give 1MHz, because clock scaling is transparent to the driver.

/* Returns the current CPU's actual unscaled running clock speed */

int cpunum_get_clock(int cpunum);

/* Sets the current CPU's clock speed and then adjusts for scaling */

void cpunum_set_clock(int cpunum, int clock);

New Windows based debugger [Aaron Giles]

Note: The new debugger is enabled as the default debugger for the next few u releases (in a debug build only) to allow feedback, it can be disabled by changing the makefile

(description of 1st update)

There are some new behaviors and new ways of doing things you should be aware of. By default the debugger no longer "auto hides". This was a remnant of the way the old debugger worked that I have gotten rid of. If you want to hide all the debugger windows, just close the "main" debug window. It will return if you break in the debugger at a future time.

The "main" window has four panes: a register list on the left, a disassembly around the current PC at the top, a console output window in the middle, and an input line at the bottom. The input line supports full editing features, and you can also use up arrow/down arrow to cycle through recently typed commands.

Hitting Enter on a blank line in the console is equivalent to single stepping once. You can also do that with F11. To run, either use the "go" command or hit F12 (or close the "main" window). To run until the next CPU, either use the "next" command or hit F6.

You can bring up multiple independent memory and/or disassembly windows by using the Debug menu. Each window can look at a different address space on any CPU. You can enter any expression (including those using registers from the CPU) into the entry line at the top of these windows in order to specify which address to begin displaying at.

I've implemented a number of useful commands in the console. Type "help" to navigate the extensive online documentation for a number of examples on how to use these features. You can do some really cool stuff now with the conditional watchpoints and breakpoints.

This is a work-in-progress, but it's pretty good now (IMHO) and stable for common debugging operations. Let me know what you like/dislike about it and what sorts of features you feel are still lacking.

(description of 2nd update)

• F12 now means "run and hide the debugger". I found this was too useful to get rid of entirely.
• F5 just means "run", keeping the debugger visible.

Enabling the debugger now forces window mode and prevents you from switching to full screen mode.

(description of 3rd update)

• Added step over/step out functionality. F10 or "over" steps over an instruction. Shift+F11 or "out" steps out of a subroutine or exception handler. Note that this feature relies on the disassembler to produce some flags indicating which instructions which need to be stepped over (generally CALLs and TRAPs) and which instructions end a step out search (generally RETURNs).
• Modified the 680x0 and MIPS3 disassemblers to support these features.
• Changed the disassembly view to back up 3 instructions when resetting (that is, the current PC should appear on the 4th line instead of the 1st line). This is not perfect, but works pretty well overall and should help see the previous couple of instructions when, say, a watchpoint is hit.
• Improved filtering of keypresses so that they don't leak into the game when you are typing in the debugger.

• note moonwalker needs a cpu core for the mcu (i8051 core?) before it will work

• Fixed a bug in the fd1094dp.c and fd1094.c decryption to allow for cotton to be decrypted [Nicola Salmoria]

• Added other hyperstone models, converted vamphalf driver to use 16-bit version [Pierpaolo Prazzoli]

• Discrete Sound Update [Derrick Renaud]

Discrete Sound Changes

• Removed the memory mapping system from the discrete inputs. It served no purpose and was never functional. It only added a layer of confusion to the code by forcing it's use on all current drivers that do not need it. If memory mapped inputs are needed in the future (not likely), then they can be added with a DISCRETE_INPUT_MAP function.
• Now the discrete inputs are written to by their node name only. eg: discrete_sound_w(NODE_xx, data)
• DISCRETE_INPUT and DISCRETE_INPUTX have been removed in favour of new easier to use input modules.
• modified all current drivers to use new code.
• moved discrete sound code from drivers and put in sndhrdw\

New Discrete Modules Added

• DISCRETE_INPUT_DATA(node) - accepts 8-bit data from discrete_sound_w. Output at reset is 0.
• DISCRETE_INPUT_LOGIC(node) - 0 if data=0; 1 if data=!0. Output at reset is 0.
• DISCRETE_INPUT_NOT(node) - 0 if data=!0; 1 if data=0. Output at reset is 1.

• DISCRETE_INPUTX_DATA(node, gain, offset, init)
• DISCRETE_INPUTX_LOGIC(node, gain, offset, init)
• DISCRETE_INPUTX_NOT(node, gain, offset, init)

• same as above, but will modify the output by the given GAIN and OFFSET. At reset the output will be INIT modified by GAIN and OFFSET.

Game Driver Changes

• skydiver - added proper watchdog. Merged memory map and added proper mirroring. Fixed coin input bug skydiver078u3yel. It's not a 100% accurate fix, but will work until I get the exact interrupt time. The current interrupt time was 100% off. It is now less then 25% off.  :-)

Windows Debugger Updates

• Fixed some compile errors [Nathan Woods]

• Misc updates [Aaron Giles]

• Added a "PC" register to the I386 core so that it should work in the new debugger
• Cleaned up stepping code
• Now refresh the display and all debugger windows after each step while stepping
• When running with the debugger window open (F5 or 'go'), now update the debugger views 4 times per second
• Can now break into the debugger even if you are focused on a debugger window
• Memory/disasm windows now come up with the currently active CPU selected by default
• added a new command: focus <cpunum>, which is equivalent to ignoring all other CPUs
• changed ignore and observe to support multiple parameters so you can say "ignore 2,3,4"
• changed ignore so that you are not allowed to ignore the last CPU
• fixed ignore behavior so that other CPUs are truly ignored
• fixed register window so that change hilights are maintained during scrolling and updates
• changed debug memory accessors so they don't log on invalid memory accesses
• tweaked the help text to indicate that help <command> works
• added a new text attribute DCA_CURRENT, which is separate from DCA_SELECTED -- the main visible difference is that the memory view editing cursor is now hilighted red instead of yellow

• In-line memory editing is now supported. To do this, I added a generic cursor concept to the view system. Each view can handle it however they want. Right now only the memory view supports a cursor. [Aaron Giles]

• Click in the memory view to place the cursor. Type over nibbles with 0-F, or use the arrow keys to navigate around. Tab cycles between the edit box and the memory editor. [Aaron Giles]

• updated psx core to show more registers [smf]

Alien Storm is fully playable

DD Crew is fully playable but requires inputs to be fixed (currently only service coin and controls for 1 player work)

Laser Ghost would probably be playable if the controls were correctly hooked up

Moonwalker requires improvements to the MCU emulation

Most of the bootlegs are still running on system16.c, please do not report bugs for these, nor for outrun or afterburner hardware.
