Specific Contributions

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

• Lord Nightmare changed the system1 driver back to using SN7489A.

• Adam Bousley fixed the road graphics, fixed the rest of the missing gfx, added collision detection, and added save states to the changela driver. Also fixed the colors.

• Zsolt Vasvari changed all drivers to use the mame_timer_* calls. Deprecated the old double-based timer calls.

• Zsolt Vasvari made changes the last few instances of rand() to mame_rand() and added a #define to prevent it from being used again.

• Dave Dribin made many of the static info_list*() functions in clifront.c public.

• Atari Ace fixed regression crashes in maxaflex.c, megadriv.c, monzagp.c, tetriunk.c, and gticlub.c.

• Wilbert Pol made some more TIA graphics and sound improvements:
  • INPT4 and INPT5 are now read when needed instead of by a timed function. This removes the need for the tia_init_pal function.
  • Improved handling of the HMOVE functionality
  • Added code to reduce the flickering caused by some Atari 2600 games
  • Improved the sound poly generation.
  • Improved the handling of POLY5_DIV3 sound mode.

• Phil Stroffolino updated the djboy driver:
  • support for djboyj; same MCU, but ROM banking bits need to be XOR'd
  • fixed state handling for game over/win transitions
  • fixes for dipswitches
  • added coinage support

• Atari Ace fixed a few places where driver code was not properly hooked up. Most cases were benign, but in a couple of instances, save state support was disconnected, and in one case it fixes a potential crash.

• Zsolt Vasvari fixed a regression in Space Raider.

• couriersud improved the frameskip behavior in the Gaelco 3d driver.

• Atari Ace fixed a palette regression in warpwarp/geebee.

• smf added support to chdman to cope with toc files created with cue2toc.

• David Haywood and ElSemi made CPS3 updates:
  • Corrected Clock speed, used idle skipping instead of reducing the clock speed.
  • Optimized some GFX functions. It now only decodes RAM based tiles when it needs to draw them, not every single time the data changes
  • Added support for CD flashing
  • Added support for alternate BIOS sets
  • Changed code to use a custom render function

• robiza found a number of additional encrypted opcodes for gussun.

• Atari Ace simplified the internal handling of BIOS sets. Instead of there being an extra structure, the BIOS information is now embedded in the ROM definition for each BIOS.

• Mike Haaland fixed the 2nd player inputs in Millipede.

• R. Belmont fixed a crash in evilngt due to missing CD image.

• R. Belmont fixed a crash in cfarm/cclown due to out-of-bounds parameter.

• R. Belmont added stricter checking in cdrom.c to prevent crashes in games when no CD-ROM is present.

• couriersud fixed regressions in dkongjr and pestplce due to incorrect memory map and rendering too many sprites.

• neoforma fixed SUBTARGET=tiny builds.

• Mike Haaland hooked up P1 joystick inputs for P2 in Upright mode in a number of black & white 8080 games. Removed cocktail settings for games where it is not appropriate. Enabled dual player game in spclaser.

• Oliver Stoneberg made x64 compilation fixes:
  • some VS2005 x64 warning fixes
  • enables the x64 porting warnings in VS2005
  • adds win_create_window_ex_utf8() to get rid of some tstring_from_utf8() usage
  • removed win_extract_icon_utf8()

• Zsolt Vasvari improved color decoding in Irem M62 games.

• James Wallace and Atari Ace synchronized MAME and AGEMAME versions of the MPU4 code. Improved Connect4 layout. Simplified much of the code.

• Wilbert Pol improved the 6532riot timer implementation. Implemented irq callback support.

• Wilbert Pol made updates to the minx CPU core:
  • Fixed TEST (94,95,96, and 97) instructions.
  • Fixed 2 MOV instructions (BE and BF).
  • Fixed one AND instruction (DC).

• Wilbert Pol simplified the interrupt handling in the z80gb core.

• Zsolt Vasvari hooked up lamps in the Afterburner 2 driver.

• Zsolt Vasvari fixed the missing sound in PGM games.

• Mike Haaland fixed Millipede sprites in cocktail mode.

• couriersud fixed the behavior of the RC filter in ddrible and ironhors.

• Pierpaolo Prazzoli added wrap around x for sprites in the m92 driver.
