Version 0.99 "DECO 156"

Released: 2005-08-06

Note that the next version of MAME will be 0.100. If you have code that depends on there being only two digits after the decimal, you had better fix it before then!

Source Changes

  • Fixed 1-bit errors in decryption keys for Crackdown and one of the D.D. Crew sets. [Nicola Salmoria, Chris Hardy]
  • Hooked up NVRAM for World Class Bowling 1.40. [Brian Troha]
  • Backed out some of the Arm core changes which broke several games.
  • Fixed the f1superb sound rom loading in ms32.c so that it doesn't crash. [David Haywood]
  • Fixed a graphics glitch in Osman. [David Haywood]
  • Updated the Taito Z driver: [Nicola Salmoria]
  • fixed road/sprite priority (cars no longer disappear when they go over a hill in Continental Circus)
  • removed bogus contcirc ROM containing 1989 copyright year
  • added PROMs
  • other minor changes

Version 0.99u1

Released: 2005-08-10

MAMETesters Bugs Fixed

  • medlanes061gre [MASH]

Source Changes

  • Undid a hack that was accidentally left in the MCR games in the last release. [Aaron Giles]
  • Fixed bug in spiders that caused bad video in cocktail mode. [Hans Andersson]
  • Fixed several problems in the H8/3002 core. Improves sound in Namco System 12 and ND-1. [cync]
  • Fixed sound banking in Go Go! Mile Smile. [Pierpaolo Prazzoli]
  • Major improvement to the YMF271 sound core: [Ville Linde]
  • Fixed timer A calculation
  • Fixed note pitch calculation
  • Added envelope generator
  • Added stereo panning and fixed other volume calculations
  • Added FM sound generation
  • Fixed crash in mystwarr games. [R. Belmont]
  • Figured out encryption key for Graplop (set 2). [MASH]
  • Rewrote the configuration reader/writer code to be more generic and easier for other subsystems to plug into. This necessitated a rewrite of the way the existing code reads config data. As a result, your game.cfg files will be invalid after this update. Your default.cfg and existing controller-specific .cfg files should work fine. [Aaron Giles]
  • Fixed all the mystwarr.c games so they pass their service mode mask ROM tests, with the exception of Metamorphic Force (it gets hung up on the road generator ("LVC") test for some reason). [R. Belmont]
  • Fixed Monster Bash (2-board version) so it works now, though the graphics are still not perfect. [David Haywood, MASH]
  • Turned off -fomit-frame-pointer in optimized builds. It was leading to crashes when used with setjmp/longjmp on Windows builds. [Aaron Giles]
  • Fixed tilemap priorities and sprites in Flying Tiger. [Pierpaolo Prazzoli]
  • Added green overlay to Meadows Lanes. [MASH]
  • Various improvements to the simple Deco 156 games: [David Haywood]
  • Modified video code to use the functions in deco16ic.c
  • Changed Osman to default to 3 buttons as per Guru's eeprom dump.
  • Namco System 22 update: [R. Belmont]
  • Hooked up MCU/CPU communications properly
  • The MCU now reads the controls in Prop Cycle, Alpine Racer, and Cyber Cycles
  • Sound effects and music are now present in all Super System 22 games

Version 0.99u2

Released: 2005-08-14

Prior versions of MAME have excluded some drivers (primarily gambling-related) for philosophical reasons. Since these games are legitimately at risk of being lost to the ages, and many of them have strong similarities to the other sorts of games MAME emulates, it has been decided to allow their inclusion going forward. The criteria for inclusion in MAME is now simply "any primarily video based arcade machine, driven by one of more CPUs," and should relieve any confusion surrounding this issue going forward.

  • Added secondary control register.
  • Hooked up IRQ control.
  • Renamed ROMs for both games to include PCB location information.
  • Some improvements to the DECO cassette games: [Juergen Buchmueller]

Version 0.99u3

Released: 2005-08-22

MAMETesters Bugs Fixed

  • hanagumi082red [Mariusz Wojcieszek]
  • rtypeleo062gre [Pierpaolo Prazzoli]
  • labyrunr080u1gre [Pierpaolo Prazzoli]
  • tricktrp061gre [Pierpaolo Prazzoli]
  • gng37b4gre [Pierpaolo Prazzoli]
  • battlane076u2gre [Pierpaolo Prazzoli]

Source Changes

  • Updates to the ST-V driver: [Mariusz Wojcieszek]
  • vdp2: added rotation in RBG0 layer (improves diehard, vfkids, vfremix, thunt, sassisu backgrounds)
  • vdp2: added 15bit RGB tilemaps (used by thunt)
  • vdp2: added opaque alpha blended bitmaps (fixes missing gfx in shienryu intro)
  • vdp2: added enable bit for RGB sprites (fixes some bad sprites in vfremix)
  • vdp2: added alpha blending for RGB sprites
  • vdp1: fixed polygon drawing
  • vdp1: added line drawing
  • sh2: fixed bug in division unit
  • sh2: added callback called when cpu reads FTCSR register (intended for idle loop skipping for slave sh2 in stv)
  • stv: added idle loop skipping for several games
  • dsp: fixed dma (fixes some bad gfx in thunt)
  • Added dsp56k CPU core and hooked it up to the Polygonet Commanders driver. [Andrew Gardner]
  • SCSI hard disk updates: [R. Belmont]
  • Added FORMAT UNIT, READ (6 byte), WRITE (6 byte), READ (12 byte), MODE SENSE, and READ CAPACITY commands.
  • Changed INQUIRY to ID as a real Seagate model, which makes MacOS much happier than a manufacturer code of "MAME".
  • Some MESS-specific tweeks to initialization.
  • Fixed all the volume table calculations in the YMF271 core. [Ville Linde]
  • SPI Improvements: [Ville Linde, Pierpaolo Prazzoli]
  • Added real coin inputs. The previously used coin input was service coin
  • Hooked up eeprom in rdft2us, rfjetus and rdft22kc
  • Fixed recent LSI53C810 update which caused the Model 3 games to crash.

[Ville Linde]

  • Fixed PowerPC recompiler so that Scud Race works again. [Ville Linde]
  • Significant overhaul of the user interface infrastructure: [Aaron Giles]
  • All user interface rendering is now cached until the end and rendered in one pass.
  • A large number of extraneous and redundant functions have been removed and replaced with a smaller set of more flexible APIs.
  • Global access to the UI fonts and colortables is now gone, they are private to the user interface code.
  • All global user interface function names have been normalized. Most importantly, usrintf_showmessage is now ui_popup.
  • Pause behavior has been redefined; instead of sitting in a tight loop, the code proceeds normally, but the CPU execution system does not advance time.
  • Code for the menus has been reworked; some menus are temporarily not available (cheats, memory cards).
  • Removed the internal display of history.dat. Cramming this kind of data into MAME's limited UI is not really useful, and viewing the history.dat information is supported by many frontends and websites. [Aaron Giles]
  • Removed the following obsolete and/or redundant command line options from the Windows build: [Aaron Giles]
-wrongorientation
-wrongfps
-gamelist
-list
-listgames
-listdetails
-listwrongmerge
-listcpu
-listcpuclass

MAMETesters Bugs Fixed

  • quarth37b1gre [Pierpaolo Prazzoli]
  • devilw36b10yel [Pierpaolo Prazzoli]
  • vulcan137b1gre, part 7 [Pierpaolo Prazzoli]

Source Changes

  • Added memory card and cheat menus back into the system. [Aaron Giles]
  • Fixed MNG recording problem that was introduced in u3. [Aaron Giles]
  • Fixed crash when running vector games that was introduced in u3. [Aaron Giles]
  • Cleaned up/normalized the naming of several core structures in an attempt to impose some order on coding conventions in the core code:
struct InputPortDefinition -> input_port_default_entry
struct InputPort -> input_port_entry
struct RegionInfo -> region_info
struct RunningMachine -> running_machine
struct GameOptions -> global_options
struct GameDriver -> game_driver
struct InternalMachineDriver -> machine_config
struct MachineCPU -> cpu_config
struct MachineSoundRoute -> sound_route
struct MachineSound -> sound_config
struct MachineSpeaker -> speaker_config
struct RomModule -> rom_entry
struct SystemBios -> bios_entry
struct GfxLayout -> gfx_layout
struct GfxElement -> gfx_element
struct GfxDecodeInfo -> gfx_decode
Plus many others along the same lines (follow the pattern). Note that this work is not yet complete. In addition, a few of the more pervasive structs (mame_bitmap, rectangle) will be left until a non-diff release (0.100). [Aaron Giles]
  • Removed -skip_disclaimer since it automatically goes away after the first time execution. [Aaron Giles]
  • Created new NMK112 ROM banking module and connected it up to a number of drivers that made use of it. Affected games are in cave.c, nmk16.c, powerins.c, quizpani.c, toaplan2.c. [Alex W. Jackson]
  • Added missing buttons to Showdown. [David Widel]
  • Fixed the PULUW instruction on the 6309 disassembler. [Nathan Woods]
  • Fixed the state save facility play better on multisession ports if initialization fails. [Tim Lindner]

Version 0.99u5

Released: 2005-08-29

MAMETesters Bugs Fixed

  • docastle093u2ora [Corrado Tomaselli]
  • sindbadm37b2gre [Pierpaolo Prazzoli]
  • mgakuen094u1gra [Roberto Fresca]
  • tdfeverj087u4gra [Roberto Fresca]

Source Changes

  • Completed renaming of core structures. Most pervasive change was "struct tilemap" is now just "tilemap". [Aaron Giles]
  • Added save state support to the Cinematronics vector games. [Buddabing]
  • Added blending to the alt tilemap code in psikyosh.c, fixing the final boss in Sol Divide. [David Haywood]
  • Improvements to the Witch/Pinball Champ '95 driver: [Sebasten Hegon]
  • The games now show some graphics (the palette seems OK) and play some music and sounds.
  • Since the controls are not yet figured out completely, they are still mapped as dipswitches.
  • An NVRAM reset is required the first time you launch Witch (via the associated dipswitch). Pinball Champ seems to automatically do this.
  • The sound part required some patching in sound/es8712.c. I disabled the hardcoded inconditional looping, and made the sound start when writing at offset 0x06 (cf patch). vmetal does not seem to be affected.
  • As far as gameplay is concerned, the ball will freeze (in game and demo mode), and I don't know why. The video hardware is not completely figured out and may be the culprit.
  • The coin in/out mecanism needs some work too.
  • Some improvements to Jolly Card: [Roberto Fresca]
  • Added extra hardware info (pinouts and dips).
  • Added the correct dipswitch to Jolly Card. Hopper and Points/pulse not tested due to preliminary driver state. The rest are working properly. Remember to delete the nvram and reinitialize to see some changes.
  • Added almost the same dipswitch to Magic Card II (Bulgaria).
  • Significant changes to the save state system: [Aaron Giles]
  • Added alternate save state pre-/post-load function types that take integer or pointer parameters. Updated several sound cores and other files to take advantage of this.
  • Made state handler registrations track like other scoped resources (timers, memory) so that registrations can occur as late as MACHINE_INIT time.
  • Added logic to detect registrations after MACHINE_INIT time and prevent saves in that case.
  • Added logic to detect when CPUs or sound chips haven't registered anything to save/load. When this happens, info is logged to error.log and saves/loads are disallowed.
  • Allocated timers are now automatically saved and restored as part of the save state. The global time is now restored as well as a bunch of CPU execution state. This should produce more reliable restores.
  • Added logic to defer saves until all anonymous timers have cleared. If a driver uses many anonymous timers it may not be possible to ever successfully save, so the operation will time out after one second.
  • Before restoring, the machine is now reset. This gives a more consistent environment for the load to occur.
  • Re-enabled save state support for YM2151.
  • Added save state support to the classic Namco sound system.
  • Added save state support to the samples sound system.
  • Removed anonymous timer usage in machine/scramble.c.

  • Fixed sprite-sprite priorities in toaplan1 games. [Pierpaolo Prazzoli]
  • Fixed background color in Jolly Jogger. [Pierpaolo Prazzoli]
  • Made input port conditionals work more generically. This necessitated a bit of a minor reorg in the input port code. Please verify that controls work as before. This change has also required a modification to how analog ports are recorded, so existing INPs may not work. [Aaron Giles]
  • Minor tweak to fix Time Crisis crash. [Phil Stroffolino]
  • Fixed spurious vectors in Top Gunner. [Mathis Rosenhauer]
  • Added new functions memory_configure_bank() and memory_set_bank() which abstract bankswitching better. This allows current memory banking states to automatically be saved for drivers that use this feature. m62.c games have been updated to use this new feature as an example. [Aaron Giles]

  • Added emulated sound and music to all NB-1, NB-2, and System 11 games, using Prop Cycle's BIOS as a substitute until the original can be trojaned or otherwise obtained
  • Hooked it up for plain System 22 games as well, but they're not interested in passing down proper commands for some reason
  • Speed-cheated all instances of the M37710/C352 sound system so CPU requirements don't go up much. This also helped back off the requirements a hair for Prop Cycle and Time Crisis
