MAME v0.144u6 is released. MAME stands for Multiple Arcade Machine Emulator. When used in conjunction with images of the original arcade game's ROM and disk data, MAME attempts to reproduce that game as faithfully as possible on a more modern general-purpose computer. MAME can currently emulate several thousand different classic arcade video games from the late 1970s through the modern era.

what's news in MAME v0.144u6:

0.144u6 ------- MAMETesters Bugs Fixed ---------------------- - 03685: [Sound] reaktor: No sound (hap) - 03568: [Crash/Freeze] lockload, gunhard: Access Violation after OK (hap) - 04189: [Gameplay] fireshrk: Inputs aren't read consistently (hap) - 04601: [Speed] vimana: game suffers major slowdowns (hap) - 04602: [Documentation] pb_l5 and clones: The correct description is "PIN-BOT..." and the exact year of production is 1986. - 04600: [Documentation] pfevr_l2, pfevr_p3: The correct descriptions are "Pennant Fever (L-2)" and "Pennant Fever (P-3)". - 04599: [Documentation] pz_f4 and clones: The correct description is "The Party Zone...". - 02234: [DIP/Input] chboxing: Unable to navigate Test Mode menu (hap) Source Changes -------------- softlist: Fix entry count tracking issue [O. Galibert] vamphalf.c: Added correct speedup for Toy Land Adventure. Demoted Mr. Kicker to not working again. There is a serious bug with the nvram handling (possibly due to a core bug) which causes the game to break entirely if you get a high score and it rewrites nvram. [Dave Haywood] i386: Made a start at Virtual 8086 Mode. Not fully working yet, though. Fixed an issue where two address or operand size prefixes would cancel each other out. [Barry Rodewald] Optimized PGM video rendering for a speedup in some video heavy cases [David Haywood] Reinstated the old KOV protection simulation given that the ARM still hasn't been dumped [David Haywood] arm7: some code reorganization, used a jump table for a small speedup [David Haywood] i386: Fixed high bits in eflags register from being changed by POPF, and VM and IF flags from changing depending on privilege level. Fixed exception error codes in protected mode. Further work on virtual 8086 mode. EMM386 will now load, but will still die a few seconds later. [Barry Rodewald] Enabling load of multi part softlist items on all available device [Fabio Priuli] ARM7: Gave ARM mode its own file & cleaned up formatting/indenting [David Haywood] : i386: Bit more progress towards getting 386 enhanced mode Windows running. [Carl] beaminv.c: added color overlay [MASH] Added support for 2 drives on IDE controller [Miodrag Milanovic] Major bitmap-related changes throughout the system: [Aaron Giles] There are almost certainly some regressions lurking. Let me know if something seems busted. Bitmaps are now strongly typed based on format. bitmap_t still exists as an abstract base class, but it is almost never used. Instead, format-specific bitmap classes are provided: bitmap_ind8 == 8bpp indexed bitmap_ind16 == 16bpp indexed bitmap_ind32 == 32bpp indexed bitmap_ind64 == 64bpp indexed bitmap_rgb32 == 32bpp RGB bitmap_argb32 == 32bpp ARGB bitmap_yuy16 == 16bpp YUY For each format, a generic pix() method is provided which references pixels of the correct type. The old pix8/pix16/pix32/ pix64 methods still exist in the short term, but the only one available is the one that matches the bitmap's pixel size. Note also that the old RGB15 format bitmaps are no longer supported at all. Converted model1, megadriv, and stv drivers away from the RGB15 format bitmaps. New auto_bitmap__alloc() macros are provided for allocating the appropriate type of bitmap. Screen update functions now must specify the correct bitmap type as their input parameters. For static update functions the SCREEN_UPDATE macro is now replaced with SCREEN_UPDATE_RGB32 and SCREEN_UPDATE_IND16 macros. All existing drivers have been updated to use the correct macros. Screen update functions are now required for all screens; there is no longer any default behavior of copying a "default" bitmap to the screen (in fact the default bitmap has been deprecated). Use one of the following to specify your screen_update callback: MCFG_SCREEN_UPDATE_STATIC(name) - static functions MCFG_SCREEN_UPDATE_DRIVER(class, func) - driver members MCFG_SCREEN_UPDATE_DEVICE(tag, class, func) - device members Because the target bitmap format can now be deduced from the screen update function itself, the MCFG_SCREEN_FORMAT macro is no longer necessary, and has been removed. If you specify a screen update callback that takes a bitmap_ind16, then the screen will be configured to use a 16bpp indexed bitmap, and if you specify a callback that takes a bitmap_rgb32, then a 32bpp RGB bitmap will be provided. Extended the bitmap classes to support wrapping a subregion of another bitmap, and cleaner allocation/resetting. The preferred use of bitmaps now is to define them directly in drivers/devices and use allocate() or wrap() to set them up, rather than allocating them via auto_bitmap_*_alloc(). Several common devices needed overhauls or changes as a result of the above changes: * Reorganized the laserdisc base driver and all the laserdisc drivers as modern C++ devices, cleaning the code up considerably. Merged ldsound device into the laserdsc device since modern devices are flexible enough to handle it. * Reorganized the v9938 device as a modern C++ device. Removed v9938mod.c in favor of template functions in v9938.c directly. * Added independent ind16 and rgb32 callbacks for TMS340x0 devices. * All video devices are now hard-coded to either ind16 or rgb32 bitmaps. The most notable is the mc6845 which is rgb32, and required changes to a number of consumers. * Added screen_update methods to most video devices so they can be directly called via MCFG_SCREEN_UPDATE_DEVICE instead of creating tons of stub functions. Added new template device_delegate which wraps a regular delegate and includes a string pointer to a device tag, which can be simply resolved later. Converted the screen_update delegates to to be based on this. Changed the mechanism by which screen formats are auto- deduced. Converted SCREEN_EOF to use these delegates as well, so now there is MCFG_SCREEN_EOF_STATIC/ DRIVER/DEVICE just like MCFG_SCREEN_UPDATE. Death to SCREEN_EOF, which was ambiguously called either at the start or end of VBLANK depending on the video flag VIDEO_UPDATE_AFTER_VBLANK. Replaced with SCREEN_VBLANK callbacks which are called both at the start and end of VBLANK, so you can operate either way, and be explicit about it. Updated all callers. Also updated screen_device to use device timers and some other minor cleanups. Beginning to implement page faults [Carl] Created new testcpu driver that shows how to develop an empty test driver that (ab)uses the core to single step a CPU executing arbitrary instructions and capturing before/after state and tracking memory. Currently this driver is always compiled, but is not referenced in mame.lst. [Aaron Giles] Cleanup of bitmap classes now that formats and bpp are dictated strictly by the type. Also added code to more aggressively align the bitmap base and rowbytes, and create a resize method which attempts to re-use existing memory rather than always reallocating. [Aaron Giles] i386: Added I/O permissions. [Carl] Added new method screen_device::register_screen_bitmap which allocates a given bitmap to match the screen size and resizes it as appropriate when the screen size changes. Updated all the obvious spots in the code where this could be leveraged. [Aaron Giles] Move allocate/resize methods in the bitmap classes down into bitmap_t because they no longer have any dependency on the bitmap format or type. Ensured that the bitmap's palette remains set across a resize call (it is lost doing an allocate). [N64] Various changes: [MooglyGuy, Happy] * Converted AI / VI / MI / RI / SI / PI into a modernized device * PI DMA now takes place after an appropriate delay to simulate transfer time - SP DMA no longer rejects transfers of 0 bytes (should transfer one 8-byte word) x87: fix for single-precision operations [Peter Farrie] Capcom ZN-1 update [Team CPS-1]: * Redumped and fixed MASK ROMs in ts2, ts2j to match real pcb (Smitdogg, The Dumping Union) * Minor fixes New games added or promoted from NOT_WORKING status --------------------------------------------------- Toy Land Adventure [f205v, The Dumping Union] New clones added ---------------- Gals Panic S - Extra Edition (Europe) [Hartenberger, arcadiabay.de] Western Gun Part II [Andrew Welburn] New games marked as GAME_NOT_WORKING ------------------------------------ Shin Nihon Pro Wrestling Toukon Retsuden 4 Arcade Edition [f205v, The Dumping Union] Touch de Uno! 2 [f205v, The Dumping Union]
