Specific Contributions

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

• David Haywood fixed an address error in Pairs Love (simulated 'buffered ram' protection?)

• David Haywood fixed an address error in Grand Cross Pinball (it's caused by the sound IRQ..but the music player was ripped out by Aaron ages ago, related?) I've disabled the IRQ rather for now rather than making a new sound core.

• David Haywood fixed a crash in debug builds running the Deco MLC games.

• David Haywood updated the Tecmo Bowl, Gaelco 2, X-Men 6p, and Megatech drivers to support dual screens.

• Nathan Woods changed VIDEO_UPDATE to return a set of flags. Only one flag is currently defined, indicating that video has not changed at all since the previous update. Most drivers should just return 0.

• Nicola Salmoria changed the MSM5205 ADPCM decoder to no longer perform bounds checking to prevent the signal from overflowing. The MSM5205 data sheet clearly states that this isn't the case, and there is no overflow protection in the chip. Also, the chip's internal DA converter is just 10-bit, even if the processed signal is 12-bit.

• Ville Linde updated the Sega Model 2 driver:
  • i960 bugfixes
  • SHARC improvements and bugfixes
  • Added HLE of the geometry DSP for now
  • Moved video hardware emulation to vidhrdw/model2.c and added preliminary 3D graphics emulation

• Ville Linde updated the Taito JC driver:
  • Improved M68040 FPU emulation
  • Improved the TMS320C51 core
  • Added 2D graphics emulation
  • Added inputs to all games
  • Properly hooked up sounds in all games

• Aaron Giles added a "fast forward" function (defaults to the INSERT key). While holding this key down, the frameskip is temporarily maxed out and throttling is turned off. This is useful for skipping over parts of the emulation.

• Aaron Giles fixed some glitchiness in font displaying where they would switch in and out of scaled modes due to rounding errors.

• Aaron Giles cleaned up handling of layout dependencies in the makefile.

• Aaron Giles fixed a bug when clipping quads in Direct3D mode.

• Aaron Giles flipped Punchout and Playchoice drivers so that screen 0 is the "main" screen.

• Aaron Giles added "left half" and "right half" to the Darius layouts so you can stretch three screens over two, though you need to explicitly set them either in the UI or using the -view0 and -view1 parameters on the command line.

• Aaron Giles changed the initial UI screens to only compute their text a single time. This reduces the CPU usage greatly when displaying some of the "game doesn't work" warnings.

• Aaron Giles added support for pausing/unpausing while showing graphics and tilemaps.

• Aaron Giles added get/set calls to control layers on a per-target basis. This allows for dynamic control of visibility of artwork layers and the option to crop to the screen. Added menu items to control these options.

• Aaron Giles removed options.use_artwork from the global options. This is now directly configured by the OSD layer.

• Aaron Giles fixed a edge case where the extra pixel on non-wrapping textures would sometimes lead to exceeding the maximum texture size.

• Aaron Giles added the concept of maximum texture size to the core renderer to prevent giant textures from being requested if the OSD layer can't handle them.
