A warts and all look through the history of MAME as described by the MAME Dev team themselves through their releases.

Version 0.80 "Terje Big Air"

Released: 2004-03-06

General Source Changes

Large Namco Update [Nicola Salmoria]

pacland: fixed sprite RAM, it was too big and included normal program RAM, causing sprites to be drawn twice.
pacland: fixed irq enable
pacland: fixed tilemap scroll offsets and sprite positions
pacland: accurate emulation of tile/sprite priority (including fix of bugs introduced when the driver was converted to tilemaps) and sprite visibility area
pacland36b16 is not a bug - colors match the real game
added SOUND_NAMCO_CUS30 for better documentation (alias for the standard SOUND_NAMCO)
drgnbstr36rc2gre
skykidd works with a patch (a dump of the CUS60A internal ROM is needed to do without the patch)
metrocross: fixed irq enable, this fixes inputs in service mode
baraduke060gre
baraduke36rc2gre, it is improved, there are still gaps left but this is correct behaviour verified on the real board
baraduke, system86: understood how sprite RAM buffering works, this fixes sprite lag but causes a glitch in rthunder (which might be correct behaviour)
system86: totally rewritten the 63701X emulation and moved it to a separate module. Fixed silence compression, this improves quality in some samples; supported volume control. -genpeitd067gre
rthundro37b14red I think is fixed; but the game still sometimes crashes when you die
rthunder, genpetid: fixed watchdog emulation, this allows entering service mode without resetting

src/windows/window.h:

Changed video_window_proc() to win_video_window_proc() and made non-static so that MESS's window proc can call it.
Changed win_init_window() to use MESS's window proc (within #ifdef MESS of course)
Added a win_suspend_directx global variable to temporarily turn off DirectX usage (used in MESS)

Discrete Sound Updates [Derrick Renaud]

Discrete Sound Changes

fixed/added more documentation of functions at top of discrete.h
DISCRETE_555_ASTABLE - changed to use common options with DISCRETE_555_CC.
DISCRETE_TRANSFORMx - fixed bug that preformed math in the wrong order.

Also added more math functions.

New Discrete Modules Added

DISCRETE_555_CC - Constant Current based 555 VCO with 8 main configurations, that automatically configure from components used.
DISCRETE_566 - NE566 simulation.
DISCRETE_COMP_ADDER - Multiple parallel capacitor/resistor circuit.
DISCRETE_DAC_R1 - R1 Ladder DAC that automatically configures from components used.
DISCRETE_MIXERx - Resistor/Op Amp mixer stage with filtering that calulates proper gains & filtering. It automatically configure from components used.
DISCRETE_SCHMITT_OSCILLATOR - VCO based on a Schmitt Inverter.

Game Driver Changes

poolshrk - Converted to new component value only code.
firetrk, montecar, superbug - Converted to new component value only code. Pulled discrete code out and put in sndhrdw\ataridis.c. montecar still needs filtering on crash sound.
atarifb, canyon & skydiver - minor changes to work with new code.
triplhnt - added component value discrete sound, but have not figured out Shot and Bear Roar video memory locations. These are needed to make sound effects work.

New Games supported or promoted from GAME_NOT_WORKING status

Radikal Bikers [Aaron Giles]
Surf Planet [Aaron Giles]

Wiggie Waggie [David Haywood]

Zintrick (hack / bootleg)

This was thought to be a prototype but actually appears to be a from an unofficial bootleg made from the CD version (see notes in driver), supported for reference incase a real prototype shows up one day.

New Non-Working games / clones supported

Lethal Enforcers [R.Belmont]

Hardware is an ugly kludge with an 8-bit CPU using 16-bit video chips, as a result there is a lot of strange banking going on making it very difficult to emulate.

Version 0.80u1

Released: 2004-03-11

General Source Changes

Improved Discrete Sound System / Sound in HitMe [Aaron Giles]

new node type DISCRETE_LOGIC_DFLIPFLOP
changed the way multichannel output is done; affects some existing drivers
support for up to 16 channels of sound

Also included is a new Hit Me driver

discrete sound support for Hit Me
fixed incorrect video (missing scanlines and inverting logic)
added controls to handle card width and game/sound speed
cleaned up memory maps

C89 compiler fixes [Lawrence Gold]

Hyperstone Cleanups [Pierpaolo Prazzoli]

Change for MESS [Nathan Woods]

src/inptport.c:

src/inptport.h:

Minor changes related to MESS's mouse device (within #ifdef MESS)

Sound supoprt in Varia Metal [Quench]

Dipswitch fixes in Varia Metal [David Haywood]

Improvements to fitfight driver [Luis Faria]

Fixed the opcode view which in some cases displayed too many bytes on 32 bit CPUs such as 68020 and Hyperstone [Bryan McPhail]

ST-V fixes [Mariusz Wojcieszek]

improved scaling tilemap backgrounds. Vfkids, colmns97 and vfremix backgrounds are better now.
fixed a problem where entering and existing service mode during game causes master / slave communication to fail. It turned out that slave cpu should be reset when it is turned off and on. This helps all games in driver.

New Clones supported or promoted from GAME_NOT_WORKING status

Invasion (clone of invaders) [Pierpaolo Prazzoli]
Super Earth Invasion (set 2) [David Haywood]
Ninja Combat (set 2)

New Non-Working games / clones supported

Air Rescue

uses an unemulated math DSP and may also require emulation of two system32 boards at once, not an easy task.

Buriki One (Hyper NeoGeo 64)

very preliminary driver, loads and decodes the gfx, attempts to run some of the code. No Video or Sound emulation is done. For now the GFX can be viewed with F4

Version 0.80u2

Various Timer Fixes, correcting some problems with SlySpy etc. [Aaron Giles]

Fixed some problems with the 32010 update [Quench]

Misc bug fixes (HuC6280 problems) [Bryan McPhail]

Some Task Force Harrier Improvements [Tomasz Slanina]

fixed sprite rendering
hacks for bg scrolling
patched some protection issues (sprites are rendered, no more strange resets)

Game is NOT playable (controls doesn't work).

Maybe something is not mapped correctly or it's problem with protection (for example , player2 buttons works durning boot - it's possible to enter service mode).

ST-V update [Angelo Salese]

fixes bitmap transparencies,adds the RBG0 layer(no scroll/roz effects yet)

adds a really preliminary window effect(just for get tile-based sprites in shanhigw) and readded the VDP1 PTM register support which has been lost in the past.

Cleaned up Capcom Bowling driver and fixed crash on reset [Aaron Giles]

IREM GA20 Update [R.Belmont]

adds the channel status readback for the GA-20, which fixes some occasional odd voice-stealing behavior I've heard playing R-Type Leo.

Reverted some Star Wars code back to older working version

New Games supported or promoted from GAME_NOT_WORKING status

Rock 'n' Roll Trivia (part 2) [Pierpaolo Prazzoli]
Scooter Shooter [Pierpaolo Prazzoli]
Dynamic Dice [Tomasz Slanina] - might be a gambling game
Lovely Cards - doesn't actually appear to be a gambling game, just gambling themed

New Clones supported or promoted from GAME_NOT_WORKING status

2020 Super Baseball (set 2) (2020bba) [HPMAN]
Spinner (Spiders bootleg) [Pierpaolo Prazzoli]
Gyrodine (Crux license?) [Pierpaolo Prazzoli / f205v]

Counter Steer [Bryan McPhail, Pierpaolo Prazzoli, David Haywood] - various things not yet understood

Version 0.80u3

Released: 2004-03-28

General Source Changes

CHDCD / Konami GV update [R.Belmont]

Preliminary CD-ROM support for CHDMAN. Input is from CDRDAO .toc/.bin images (cdrdao.sourceforge.net). CDRDAO comes with utilities to convert CDRWIN .cue/.bin images to .toc/.bin format.
Intel Flash ROM emulation support
CDROM emulation primitives, including Red Book audio playback
CDROM support for the AM53cf96 SCSI controller
Konami GV System driver. GV System is identical to a home Playstation/PSOne console, except the CD-ROM is SCSI instead of proprietary.

Stuff still in progress:

The SPU emulation needs a lot of help, especially on Wedding Rhapsody. smf is working on it.
The SCSI CD-ROM emulation needs to be separated out from the AM53cf96 if we ever emulate other SCSI controllers or CD-ROM drives.
CHDMAN doesn't output anything useful when you extract a CHD-CD. It should write out a CDRDAO image.
Audio tracks on CDs are not compressed at present (or more accurately they're gzip compressed, which is useless). The plan is to use FLAC at some point.

Misc Fixes [Nathan Woods]

src/mame.c:

src/mame.h:

src/windows/config.c:

Changed options.savegame to be a string. If this is a one character string, then the save state is loaded as before. If it is a larger string, then cpu_loadsave_schedule_file() is used.

src/state.c:

src/state.h:
