Et voil\u00e0 la nouvelle version de Mame attendu depuis quelques jours. Voici les news:<\/p>\n
Emulation of Sega FD1094 encrypted 68k CPUs, this will allow for
\nsignificant progress in the emulation of the remaining encrypted Sega games.
\nNote that we require working CPUs to extract encryption data from in order
\nto 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.)
\n[Charles MacDonald – extracting data from CPUs,
\nNicola Salmoria – decryption code]<\/p>\n

\n* DISCRETE_INTEGRATE – various op amp integration (ramp) circuits.
\n* DISCRETE_OP_AMP_TRIG_VCA – Did not know what to call this. \ud83d\ude42
\nBasically it is a programable voltage controlled amp. But uses only an on\/off trigger.
\nIt has resistors to select the rise\/fall times. Also it is not a true VCA.
\nIt actually adjusts amplitude by clipping more\/less off the bottom of the
\ninput signal. But it is a common circuit.<\/p>\n
\nHooked up watchdog timer.<\/p>\n
\nwatchdog and set to proper time using new MDRV_WATCHDOG_VBLANK_INIT function.
\n* firetrk, montecar, superbug, pacman, polaris – changed watchdog to proper
\ntime using new MDRV_WATCHDOG_VBLANK_INIT function.
\n* galpania, galpanib – changed to MDRV_WATCHDOG_VBLANK_INIT because these
\ngames need watchdog init at game start.<\/p>\n
\nprevious watchdog functionality is retained. Only define 1 of the 2 watchdogs
\nper game. If both are defined then MDRV_WATCHDOG_VBLANK_INIT will be used
\nonly.<\/p>\n
\nMACHINE_DRIVER_. watch_count is the # of vertical blanking intervals
\nbefore a forced reset. If the time is unkown then you can use these defaults:
\nDEFAULT_60HZ_3S_VBLANK_WATCHDOG or DEFAULT_30HZ_3S_VBLANK_WATCHDOG<\/p>\n
\nMACHINE_DRIVER_. time is the time in seconds before a forced reset.<\/p>\n
\nwatchdog_enable(0 or 1) – used to 0=disable or !0=enable.<\/p>\n
\nTIME_OF_74LS123(r,c)
\nr is in Ohms. c is in Farads.
\nc must be greater then 1000pF to use this function<\/p>\n
\n-[no]skip_validitychecks
\nForces MAME to skip doing the code validity checks. The default is
\nOFF (-noskip_validitychecks).
\nThis 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.<\/p>\n
\nFixed qdrmfgp broken by cleanup in u3 [Olivier Galibert]
\nFixed cut and paste error in chdman [Ren\u00e9 Single]
\nFixed mayday inputs [Stefan Jokisch]
\nFixed Puzzle Club dips [Brian Troha]
\nInput Port System Update [Aaron Giles]
\nPORT_INCLUDE() works the same as before.<\/p>\n
\nmatching entries in the previous definition, allowing you to overwrite
\nthem with new stuff.<\/p>\n
\nport_tag_to_handler16()
\nport_tag_to_handler32() — these 3 new functions take a tag string, find the
\ninput port, and return the appropriate handler. They can be used in AM_READ,
\nso instead of:<\/p>\n
\n* added explicit casting to the memory handler width when computing
\nthe shifted data\/mask values for read\/write handlers — this should in
\ntheory fix R. Belmont’s 64-bit issues<\/p>\n
\nfunctions to allow dynamic installation of match\/mask (AM_SPACE-style) memory
\nranges –this should satisfy Frank P’s request for the astrocade driver<\/p>\n
\nwith an AM_MASK does not expand the explicitly-specified mask value — this
\nshould fix dwidel’s problem getting Pac-Man accurate<\/p>\n
\nexplicitly specified a mask value via AM_MASK — this should allow
\nmirroring via AM_MASK if you want to, though AM_MIRROR is still preferred<\/p>\n
\ngoing in\/out of service mode.<\/p>\n
\nwould not remain disabled after a watchdog_enable(0) in some conditions.<\/p>\n
\nscaling factor will still apply. eg. If you force the CPU to change clock to 1MHz
\nwhile the scaling is at 50%, the effective CPU speed will be 500kHz.
\nThen reading the clock speed will give 1MHz, because clock scaling is transparent to the driver.<\/p>\n
