Specific Contributions

The known contributions for this version are, in the order specified in the whatsnew:

• Sound support for Burger Time (Midway) was added.

• The sound CPU in Scramble (Stern) was hooked up, though it produces incorrect audio.

• The AY-3-8910 audio chip emulator was switched to using the default clock rate for Crazy Climber (US), Crazy Kong (set 1) and Bagman (Stern set 1).

• Ron Fries' POKEY audio chip emulator was integrated into the MAME code base, adding sound to Centipede (revision 3).

• The speed in Burger Time (Midway) was adjusted to be more accurate to the real board; previously, it was running at approximately half-speed.

• Valerio Verrando provided a 288x224 video mode definition to be used with Rally X (Midway).

• In-game slowdowns in Rally X (Midway) and Bagman (Stern set 1) were fixed.

• Mike Cuddy and Mirko Buffoni improved the colors in Pooyan (Stern).

• Nicola Salmoria fixed a bug in Pooyan (Stern)'s DIP switches.

• The colors in Moon Cresta (Nichibutsu) and Moon Quasar were verified to be accurate.

• Support for the blinking background stars in Scramble (Stern) and Super Cobra (Stern) was added.

• Ville Laitinen fixed the inputs in The End (Stern) and Scramble (Stern).

• Ville Laitinen fixed sprite priorities in Congo Bongo.

• Doug Jefferys submitted color PROMs for Crazy Kong (set 1).

• Mike Coates fixed the graphics in Carnival (upright), though it is still unplayable.

• Bernd Wiebelt suggested the addition of the "-vesascan" option, which upscales the image and adds scanlines, at the cost of speed.

• Multiple CPU support was added.

• The Zilog Z80 and MOS 6502 CPU cores were modified to cache pending interrupts.

• *_vh_start(), *_vh_stop(), *_videoram_w(), and *_colorram_w() were moved into the generic video hardware framework, meaning that only games that need to do anything special have to override the functions.

• Sample streaming code was fixed to support more than one sample being played simultaneously.

• A bug in drawgfx() was fixed which allowed transparent, non-remapped copies to be written outside of the clip region.
