Specific Contributions

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

  • couriersud modified discrete_sound_r to let it inquiry any node:
    • The return type is UINT8, consequently the designer needs to ensure that the node delivers adequately scaled data.
    • Input nodes allow the input data to be scaled. The return value is the node value *after* scaling.
  • Derrick Renaud started making a more accurate simulation of DISCRETE_566 based on testing of a real IC. This made the rest of Sky Raider sounds work.
  • Guru completed the dump of the Gun Survivor 2 cart.
  • Andrew Gardner hacked in the dsp56156's "Long Interrupts." Added SUB opcode. Polygonet Commanders now goes in-game!
  • Harmony fleshed out the SCC68070 definition in m68k core, for CD-i use in MESS.
  • R. Belmont added the PMOVE instruction (move to/from PMMU) to the m68k disassembler.
  • couriersud optimized the discrete sound system:
    • More LS624 optimization, replace pow(10, x) by pow10(x).
    • Mixer loop optimizations.
  • couriersud improved discrete performance for mario:
    • Pow to exp : 5%
    • Parallel tasks : 45%
    • Minor tweaks.
  • R. Belmont updated the M680x0 core.
    • Added CPU types 68EC030, 68030, and 68EC040.
    • Started 030/040 PMMU, including stubbed PMOVE.
  • Aaron Giles fixed up RAM bank names to prevent crashes with memdump. Extended explicit banks to 96.
  • MetalliC fixed and improved the multfish.c driver:
    • Hooked up inputs for Roll Fruit.
    • Added hopper emulation, payout now works.
    • Added information on how to initialize Roll Fruit.
    • Added in missing rom to a few MultiFish sets.
  • Derrick Renaud optimized speed and added new operating modes to DISCRETE_555_MSTABLE.
  • Team Japump!!! fixed ROM name of warpwarp. Also removed 4th program ROM which is not present on real board.
  • Aaron Giles allowed memory references to explicitly specify logical or physical access by prepending with an 'l' or 'p'. Logical remains the default. Example: ppb@1000 = physical program space byte at address $1000. ldw@2000 = logical data space word at address $2000. Changed cheat finder to explicitly reference physical memory when writing out new cheats.
  • Stefano Ronco added simple system for auto-detecting cheat-worthy RAM areas.
  • David Haywood added a NULL check to prevent MAME from crashing if a new input device as connected at runtime.
  • Atari Ace added more _NAME macros to be consistent with the standard naming conventions.
  • David Haywood removed old master system code from megaplay.c, megatech.c, segae.c and updated the drivers to use more recent implementation (from HazeMD).
  • couriersud removed capacitor aging code and assumed range input is gnd for all 74LS629.
  • couriersud implemented m:n logic for buffered task nodes in discrete sound.
    • Preparation work so that a task node output buffer may be read by more than one following task.
    • Target: implementation of task groups: tasks in a task group run parallel, task groups serial. The current main task may than just be task (in the last task group).
  • Atari Ace added static qualifiers where possible throughout the code.
  • couriersud implemented discrete task groups:
    • DISCRETE_TASK_START now requires a parameter TASK_GROUP (>=0, <=9).
    • Tasks are scheduled in the order of their task group.
    • Nodes are automatically buffered between task groups.
    • Discrete core determines nodes which need buffering to minimize overhead (information in DISCRETE_LOG).
    • A discrete block list now must put each stepped node into a task if it uses tasks.
    • Drivers not using tasks will get one task allocated automatically.
    • Updated drivers accordingly.
    • Some more constification.
  • Atari Ace optimized tab removal in srcclean.
  • Mamesick centralized color definitions and made some colors more specific.
