Specific Contributions

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

  • couriersud provided discrete sound updates:
    • Fix comments for DISCRETE_TRANSFORM.
    • FatalError if formula is bad.
    • Fixed two bugs in DISCRETE_RCDISC3.
    • Fix some ugly bugs around DISCRETE_FILTER_SW:
      • No more iterations.
      • The CD4066 internal resistance largely determines sound amplitude. This may vary significantly depending on VCC and type (74HC, 74HCV, CD4066, ...). The current choice makes scramble sound "about right".
    • Added some profiling code for discrete tasks.
    • Added DISCRETE_INPUT_BUFFER to use a stream to buffer an input node. For input nodes with a lot of writes this prevents a stream_update on the whole discrete module which is very ineffective. Instead, the data is buffered and the discrete emulation can process a lot of samples in one go later.
    • Added disc_syc.c as a container for core modules (output, task).
    • Discrete wav and csv logs now are treated as nodes.
    • Added DISCRETE_START and DISCRETE_STOP functions to be called at device start/stop.
    • As a side effect, profiling measures log overhead as well.
    • DSO_TASK_END now builds it's own dependence list.
      • Now simply DSO_TASK_END() ends a task.
    • Added node parameter to RC_(DIS)CHARGE_EXP.
    • Added const where appropriate.
    • Removed some dead code.
  • Brian Troha verified the color BPROM for Royal Card Pro v2 to be correct.
  • Atari Ace de-globalified sound.c and input.c.
  • Roberto Fresca provided improvements to Noraut Poker driver:
    • Corrected CPU clock to Xtal/8.
    • Discovered 3 new I/O lines coming from PPI-2, PC0-PC2. They are mixed with the handshake ones.
    • Added the READOUT button to noraut12 games.
    • Splitted the main machine driver to cover 2 different Noraut systems.
    • Added partial support for PPI-2, PC0-PC2 output lines on noraut11 games.
    • Figured out other remaining I/O lines.
    • Added new handlers to simulate the handshake lines. Still need real support through PPI-2.
    • Updated technical notes.
    • Rerouted norautp and norautjp READOUT button to its own place.
    • Routed the whole video RAM access through PPI-2. (bypassed the handshake lines for now).
    • Merged back the noraut machine drivers after the 3rd PPI connection.
    • Added Low Level Hopper manual input.
    • Added a new machine driver for extended hardware. It has 2 jumpers that cut the a14 and a15 addressing lines.
  • Quench provided fixes to the PIC16C5x CPU core:
    • Indirect addressing was not taking into account special purpose memory mapped locations.
    • 'iorlw' instruction was saving the result to memory instead of the W register.
    • 'tris' instruction no longer modifies Port-C on PIC models that do not have Port-C implemented.
  • Quench added difficulty DIP to BigTwin.
  • Tomasz Slanina and David Haywood provided various fixes for Shogun Warriors:
    • Extracted tables required for Shogun Warriors to work.
    • Decrypted + verified table data for Shogun Warriors.
    • Marked 2 graphic roms in Shogun Warriors as BAD_DUMP.
    • Temporarily added a hack to the collision function to only use the B.Rap Boys code if the game is B.Rap Boys until we have a single function that works with both.
  • Anonymous provided SuperFX updates:
    • Fixed disassembly of LMULT/FMULT ops.
    • Fixed reads using LDW/LDB.
    • Fixed writes using STW/STB.
    • Fixed SBC carry behaviour.
    • Fixed GETC ROM access behaviour.
    • Some SuperFX games begin to show things in MESS.
    • At least partly fixed PLOT and RPIX behavior. This fixes many gfxs in Star Fox and Vortex, but no polys yet.
  • David Haywood simplified kaneko16 decryption functions by working out what each of the bits does and removing game specific references. Re-based the decryption tables as a result. End result is verified to be the same.
  • Guru added redumped u6 GFX rom to kaneko16, fixes Geisya and Sumo.
  • couriersud fixed circus charly slowdowns:
    • use SOUND_DAC device to "buffer" data and avoid 1 sample updates for discrete part.
    • this is related to "03401: circusc and clones: Slowdown in attract mode with DIP SW "Demo Sounds=ON"" though I do not consider it a bug, but a implementation optimization.
  • robiza added different TOD implementation for CIA6526 and CIA8520.
  • David Haywood fixed a small bug with kaneko16 graphic decoding and removed old comment about bad sound banking.
  • Harmony provided SuperFX updates:
    • Inlined a number of functions for possible speed increase.
    • Removed some memory buffering cruft, to be re-added later.
    • Fixed behavior of ASR opcode.
    • With additional MESS-side changes, Stunt Race FX is playable, and Vortex shows much more.
    • Hooked up RAM and ROM buffering.
    • Inlined several more functions.
    • Removed debug spew.
    • Added the ability to define an external IRQ line callback, and hooked it up to the 65C816.
    • Fixed flag calculation for HIB opcode.
    • Hooked SuperFX chip up to the SNES machine driver.
    • Fixed carry handling in ADC, ADCI, SBC and SBCI opcodes. Fixes many SNES SuperFX bugs.
  • Sandro Ronco added some basic cheat search functionality to the debugger, allowing searches on various memory sizes.
  • Pugsy added 'Reload All' option to the cheat menu.
  • Pugsy enabled display of cheat comments from within the cheat menu. Press the SPACE key to toggle display.
  • hap tweaked the shadows in twin16 to be slightly darker.
  • Aaron Giles added new function mame_fclose_and_open_next() which will close a file and then keep searching the searchpath for the next valid file. Did some internal rearranging in fileio.c to make this work.
  • Aaron Giles changed cheat search so that it loads *all* cheat files in all search paths. Note that it is easy to end up with duplicate entries this way. Some currently disabled code is present which filters out duplicates, but the logic for doing this is quite unclear with the presence of text-only cheats, which is why the code is disabled for now.
  • R. Belmont updated the M377xx core: fixed CLB/SEB when not in bank 0.
  • Harmony fixed numerous opcodes in the AVR8 core.
  • Harmony enabled alternate register naming in the MIPS core.
  • Lord Nightmare added loopback mode and counter/timer modes 3 and 6 to 68681 DUART, self-tests now pass in dectalk in MESS.
  • R. Belmont and Harmony provided SNES updates:
    • Corrected ROM loading behavior for SuperFX games.
    • Added more ROM mirroring needed by certain SuperFX 2 games.
    • Corrected the behavior of certain bit-restricted SuperFX registers. Doom, Yoshi's Island, Dirt Trax FX and Voxel Demo show things now.
    • Improved S-DD1 emulation, neither game using S-DD1 boots yet.
  • Curt Coder added preliminary Zilog Z8 CPU core for MESS.
  • Tafoid cleaned up drivers that write files which are not being actively developed. Also, commented our or changed the printf-ing of some messages to LOGERROR.
  • Harmony made numerous corrections to SNES S-DD1 chip emulation, SFA2 and Star Ocean still do not boot.
  • Roberto Fresca updated the Golden Poker driver:
    • Added 2 new Witch Card sets.
    • Reworked inputs for Witch Card (german set 1).
    • Created new inputs for Witch Card (english, witch game, lamps).
    • Added and connected lamps for both sets.
    • Added minimal bet and 50/60 Hz. switches to both sets.
    • Added DIP switches info for Witch Card (german, set 2).
  • David Haywood provided a Naomi/Atomiswave video hardware update:
    • Basically the region array is processed, and the data from the accumulation buffer where we render is now copied into the framebuffer depending on the tiles specified in the tile list. This isn't full 'tile-based rendering' as that would require more work on the preprocessing side, and writing out the data pointers and data in real formats, however it's a step in the right direction.
    • Currently only 565 formats are supported for both framebuffer write and framebuffer read. The accumulation buffer is alwys 8888, data is converted down to the specified format. The real accumulation buffer is 32x32 and filled per tile, ours is still full screen.
    • The video update now just displays the framebuffer using the framebuffer read parameters specified (again only 565 is currently supported). This allows the Atomiswave bios screens and the rendered output to co-exist.
  • Robbbert provided Jaguar updates:
    • Added RGB 24-bit pixels (for Iron Soldier).
    • Added depth 0 and 1 to scaled bitmaps (for Val Disere Skiing).
    • Preliminary work on PIT support.
  • iq_132 got vandykeb up and running.
  • David Haywood added verbose debug logging for the little robin 'vdp' writes in preparation for looking at it further.
  • AGEMAME improved the connect4 layout.
  • David Haywood fixed the plane order in the gfx deodes for Black Touch '96 sprites, and Poke Champ sprites.
  • David Haywood improved the sprite emulation in Black Touch '96 (still wrong tho).
  • Gabriele Gorla fixed LOOP instructions in 16-bit mode in the i386 core.
  • Aaron Giles fixed stupid unidasm bug that double-counted bytes.
  • R. Belmont, Guru, Deunan Knute and Cah4e3 provided a major Naomi/Atomiswave update:
    • Emulated Atomiswave coin slots and standard Dreamcast controller. Non-lightgun games without other problems are now playable.
    • Added protection data to Moero Justice Gakuen, Heavy Metal Geomatrix, WWF Royal Rumble, Gigawing 2, Toy Fighter, and Guilty Gear X (all are now playable but still marked GAME_NOT_WORKING due to general Naomi concerns).
    • Completed partial dumps: Derby Owners Club II, Slashout, WWF Royal Rumble, Gigawing 2, Moero Justice Gakuen, Wild Riders, Virtua Fighter 4 (cartridge).
  • couriersud and Aaron Giles renamed osd_profiling_ticks() to get_profile_ticks(). Moved implemention into inline functions in eminline.h and the ei* functions.
  • Aaron Giles added 'options' parameter to the CPU_DISASSEMBLE prototype. For now, the debugger always passes 0 for this. unidasm has been updated to accept a mode parameter, which is passed for the options.
  • Aaron Giles added PORT_CROSSHAIR_MAPPER() allowing you to specify an alternate, non-linear mapping function from the raw crosshair value to its position onscreen.
