* [[Nicola Salmoria]] added real shadows to some Konami games (88 Games, Chequered Flag, X-Men, Asterix, Surprise Attack, Sunset Riders, etc.).

* [[David Haywood]] added real shadows to some SNK games (Ikari Warriors, Victory Road, etc.).

* [[Luca Elia]] added real shadows to Cisco Heat and F1 Grand Prix Star.

* [[Nicola Salmoria]] fixed some protection related issues in Sunset Riders.

* [[Nicola Salmoria]] fixed colors in Major Title 2.

* [[Nicola Salmoria]] fixed colors in Berlin Wall.

* [[Mathias Rosenhauer]] fixed the radar display in Aztarac.

* [[Bryan McPhail]] and [[Nicola Salmoria]] decrypted the sound CPU in Gunforce, Blade Master, Lethal Thunder, Undercover Cops, Mystic Riders, Major Title 2, Hook, R-Type Leo, In the Hunt, and Perfect Soldiers.

* [[Aaron Giles]] fixed a EX550x bug that caused Taito F3 and Incredible Tech games to sound bad.

* [[Aaron Giles]] fixed the remaining issues in Slapstic emulation.
** Pit Fighter works to the end
** Rampart works to the end
** Tetris now uses the slapstic code

* [[Bryan McPhail]] fixed the protection in the original Robocop.

* [[Nicola Salmoria]] decrypted the original Popeye.

* [[Scott Brasington]] fixed the Free Play mode in Galaga.

* [[Fabrice Frances]] added support for the target data extracted from the laserdisc to MACH 3.

* The Windows port is now called "MAME" (instead of "MAMEW"). The DOS port is called "DMAME".

* [[Paul Priest]] and [[Bernd Wiebelt]] improved the CLI support in the Windows version:
** config option for steadykey (default: OFF)
** parse debug.ini in debug builds
** mamew \anywhere\roms\pacman.zip works
** improved -log option
** mame will now parse argv[0].ini instead of mame.ini. i.e. if the mame executable is called "m37b17.exe" it will parse m37b17.ini instead of mame.ini

* [[Aley Keprt]] added support for C64/Atari/Sinclair joysticks connected via DB9 or Turbografix interface to the DOS version.

* Big changes to the palette system. 8-bit modes are no longer supported, only 16-bit ones are used. 8-bit support may be removed from the OS dependant code; the core will never ask for an 8-bit deep screen. 8-bit bitmaps could still be used though.

* Palette compression has been removed. palette_recalc(), palette_transparent_pen and palette_used_colors* [[]] are not available anymore. Drivers that relied on PALETTE_COLOR_TRANSPARENT for transparency effects must be rewritten to implement them differently. As a result of this, all games using the Taito TC0480SCP video chip, and all Taito F3 games, are broken in this release.

* tilemap_update() is gone. Everything is handled by tilemap_draw().

* IMPORTANT CHANGE FOR PORTERS: the OS dependant code is now required to guarantee, in 16-bit palettized mode, that Machine->pens* [[i]] == i. The "pens" argument to osd_allocate_colors() will be NULL, actually it has been renamed "rgb_components" since direct RGB modes are the only ones that will pass that argument.

* Remove VIDEO_MODIFIES_PALETTE and the "modifiable" parameter from osd_allocate_colors().

* [[Nicola Salmoria]] added new flags VIDEO_HAS_SHADOWS and VIDEO_HAS_HIGHLIGHTS that automatically extend the palette creating a darker(brighter copy for shadows handling. palette_set_shadow_factor() and palette_set_highlight_factor() allow to control the adjustment to apply (shadow can be > 1.0, making it an highlight, and highlight can be < 1.0 making it a shadow - the names are just conventional).

* [[Nicola Salmoria]] added the function palette_set_brightness(), allowing selective control of palette brightness independently of the palette RAM contents.

* MachineDriver.color_table_len can now be 0, meaning that the colortable is a 1:1 mapping from the palette. Note that you CANNOT use this feature if you use TRANSPARENCY_COLOR; but of course, if you need TRANSPARENCY_COLOR you'll not have a 1:1 colortable.

* [[Phil Stroffolino]] added the function tilemap_draw_roz().

* [[Aaron Giles]] added the function auto_malloc(); this is the same as malloc(), but the memory is automatically freed when the driver exits.

* osd_bitmap.line is now a void ** to prevent confusion.
