WIP:
  • 21st December 2007: Guru - A huge box arrived today. That 19.75kg box looks mighty impressive, although I'm not sure that all of it is going to be useful. Some could be alt. versions but most don't work so I'll need to dump all of these before I can tell exactly what they are. It contains Pacman PCB with Two Bit Score's 'Super ABC' upgrade kit (on original Midway PCB) and others. Thanks to Tingoes for sending these out.
  • 0.111u3: Nathan Woods and Aaron Giles updated input port tokenization for MESS. Added support in MAME for "configuration" switches which are separate from dipswitches. These can be used to configure aspects of the game that don't correspond to dipswitches. Modified pacman.c to use configurations to control the speedup options.
  • 0.105u2: David Widel added clone Abscam.
  • 0.92: smf added clone Puckman (Falcom?).
  • 0.90u4: Dave Widel added clone 'Caterpillar Pacman Hack' (1982). Dave consider this sig. since it came in it's own cab and they did change some of the music. Changed region gfx2 to gfx1 ($1000).
  • 0.88: Derrick Renaud changed watchdog to proper time using new MDRV_WATCHDOG_VBLANK_INIT function in Pac-Man.
  • 0.84u6: Aaron Giles added clones PuckMan (Japan set 1 with speedup hack) and Pac-Man (Midway, with speedup hack). Removed existing speedup cheat hack from Pacman/Ms Pac Man as the way it was implemented in MAME is NOT how it was implemented in the arcades. I have added the hacked software ROMs as three separate sets for Puck Man, Pac Man, and Ms. Pac Man. These hacked ROMs do not let you control the speed of the game with a button; the game is always fast, and Pac Man is faster than the ghosts. Also added a fake dipswitch to control the equivalent of the hardware version of the speedup hack. It can be set to "Disabled", "Enabled Always", or "Enabled with Button". Note that this hack speeds up everyone, including the ghosts, as the original hack did.
  • 0.74: Added clone Hangly-Man (set 3).
  • 7th September 2003: Manuel Abadia added another clone of Hangly-Man to the Pacman driver.
  • 0.69: Dave Widel added clones Newpuc2 (hack 1980) and Newpuc2 (set 2). This hack was common in the arcades, it has intermissions between each maze and a slot machine every 3 mazes.
  • 0.68: Dave Widel added clones Piranha (GL (US Billiards License)) and Piranha (older). Renamed (piranha) to (piranhah).
  • 0.65: Added clone Joyman (hack).
  • 20th June 2002: David Haywood resubmitted a Pac-Man bootleg.
  • 19th June 2002: Dave Widel added two new versions of Piranha to the Pac-Man driver.
  • 26th February 2002: Mike Coates added another bootleg of Pac-Man Hearts to the Pac-Man driver. Stephane Humbert fixed the dipswitch settings in it.
  • 0.53: Renamed (pacman) to (puckman), (pacmanjp) to (puckmana), (pacmanm) to (pacman), (npacmod) to (puckmod) and (puckman) to (newpuckx).
  • 0.35b13: Gerald Vanderick added clone Hangly-Man (set 2). Changed descriptions: 'Pac Man (set 1/2)' to 'PuckMan (Japan set 1/2)', 'Pac Man (Midway/harder)' to 'Pac-Man (Midway/harder)', 'Hangly Man' to 'Hangly-Man', 'Puck Man' to 'New Puck-X' and 'Miss Pac Plus' to 'Ms. Pac-Man Plus' etc.
  • 4th May 1999: Gerald Vanderick added another Pac Man clone, and an Arabian clone.
  • 0.35b9: Allard van der Bas added clone Pac Man (harder?). Renamed (pacman) to (pacmanm) and (namcopac) to (pacman). Changed description of clone 'Pac Man (Namco, alternate)' to 'Pac Man (set 2)'.
  • 15th March 1999: Victor Trucco added a Pacman clone.
  • 12th March 1999: Allard van der Bas added a new Pacman clone and Van Van Car to the Pacman driver.
  • 0.35b1: Added clone Pac Man (Hearts) (hack 1981) from a zillion people.
  • 0.34b4: Changed description of clone 'Pac Man (bootleg on Galaxian hardware)' to 'Pac Man (bootleg on Pisces hardware)'.
  • 0.30: Nicola Salmoria and Aaron Giles completely rewritten the Namco waveform audio subsystem. This gets rid of some artefacts in Pac Man (eating a ghost) and Ms Pac Man (eating dots while a fruit is bouncing).
  • 0.29: Nicola Salmoria added clone Pac Man (bootleg on Galaxian hardware). Sean Gugler added in some games (e.g. Pacman, Galaxian, Rally X) the NumLock and CapsLock leds, they emulate the 1 player/2 players start lamps.
  • 0.28: Merged Pengo and Pac Man vidhrdw driver. The speedup cheat in Pac Man can now be permanently set to ON from the dipswitch settings menu.
  • 0.27: Added clone Pac Man (Namco, alternate).
  • 0.26a: Mirko Buffoni worked with the wrong source, now everything is back to normality in Pacman.
  • 0.26: Mauro Minenna introduced a new option (-dir4) that simplify the use of the joysticks to be connected on the keyboard. This modify resolves the problem of diagonal direction in games such as PacMan, Popeye, and Kung Fu Master.
  • 0.18: Sprite placement in Pac Man, Ms Pac Man and Crush Roller should now be arcade perfect. Thanks to Richard Davies who verified it on a real machine.
  • 0.15: Brad Oliver fixed a illegal memory accesses bug in games using 224x288 and 288x224 modes (Pengo, Pac Man, Rally X). Hiscore save in Pac Man.
  • 0.06: Fixed staccato notes in Pacman and other games using the same hardware. There are still some minor glitches (especially in Ms. Pac Man) but Pac Man tunes are now very close to the original.
  • 0.02: Added clone Puck Man (hack 1980).
  • 0.01: Nicola Salmoria added Pac Man (Midway 1980). Blinky and Pinky seem to be shifted one pixel to the right. This is really annoying, but I can't seem to be able to understand why. Maybe there is an additional "sprite offset" register somewhere? Or did the original just behave this way? Note that we can't fix it by just moving sprites 0 and 1 one pixel to the left, because when Pac Man eats a power pill the sprites order is changed so that Pac Man is drawn over the ghosts. It becomes sprite 0, and Blinky becomes sprite 4.
