Specific Contributions

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

  • BUT fixed a buffer overflow in K054539.
  • kingshriek made SCSP improvements:
    • Added logarithmic envelope table
    • Set envelope level to start at 0x17f in the ATTACK state (0x3ff-0x280) as per Neill's notes
    • Changed EG_SHIFT from 8 to 16 - more precision is needed to differentiate the longer decay envelope times
    • In the DECAY1-->DECAY2 transition, changed the "<=" to "<"
    • Decreased the output of the effect out mixer a bit
    • Fixed unaligned 16-bit samples
    • Prevented keyoffs from killing slots when already in the release state
    • Envelope steps in the attack state are apparently exponential. To account for this, I change the envelope output to linear for attacks.
    • Change the release rate calculation to use the decay table instead of the attack one.
  • Wilbert Pol fixed a uninitialized variable in h6280 core.
  • James Wallace added meter support to the Cobra games. Cleaned up some of the steppers code.
  • Atari Ace const-ified a number of data structures in the MAME system.
  • Ville Linde added PowerPC 604 processor support. Moved PowerPC opcode tables to the CPU context to allow multiple simultaneous processors with different opcode tables.
  • couriersud updated the dkong driver:
    • Added configuration switch to change palette between TKG02 (radarscp conversion) and TKG04 (dkong 2board)
    • Added speech support (samples) to radarsc1
    • Fixed sound for drakton and strtheat
    • Hooked up and written 8257 dma controller
      • All dkong and dkongjr based games now use the 8257
      • All epos and 2650 based games now use the 8257
    • Fixed 2650 games to use dkong audio as well - only cpu replaced by addon board ...
    • Updated game flags and added missing rom entries
    • straightened memory maps
    • Fixed bug in dkong3b memory map
    • Externalized sound drivers to MACHINE_START in audio/dkong.c
    • DAC Filter now uses lowpass sallen key filter
    • Reorganized INPUT_PORTS
    • Added Dip-Switch locations to 8ballact
    • Fixed 8ballact according to conversion manual
    • Reorganized code
  • couriersud corrected a potential issue if more than one 8039/8035 is used by a driver. Also should fix a potential inconsistency between saving and loading a state.
  • Aaron Giles added an assert to ensure that the sound clear latch value is only set at init time, since its value is not saved.
  • Aaron Giles modified src2html to sort by filename rather than assuming that the osd file finding routines would do so.
  • Aaron Giles fixed a memory system regression caused by recent optimization. Fixed another bug uncovered as a result in the decrypted opcode management.
  • Aaron Giles made more Zeus improvements. Converted over to 64-bit data and simplified the logic to work more like the hardware.
