Specific Contributions

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

  • Derrick Renaud and Frank Palazzolo added new Discrete Sound Functionality DISCRETE_OP_AMP_FILTER - properly emulated DISC_OP_AMP_FILTER_IS_BAND_PASS_1M type filter. Used by many games. Re-wrote atafifb and abaseb to use component value only code and use new filter.
  • Nicola Salmoria updates the Super Qix driver:
    • manually repaired the ROM code and added support for the I8751 MCU, so the two original sets work.
    • swapped sqix and sqixa, because the the former was dumped from a bootleg board (though there's no reason to believe the ROMs were modified, so I didn't mark it as bootleg)
    • merged with pbillian
    • fixed pbillian/hotsmash sample playback
    • fixed pbillian MCU simulation and inputs
    • improved hotsmash MCU simulation, the game is playable now though still incomplete.
  • Nicola Salmoria updated the Bubble Bobble driver:
    • removed the 68705 CPU emulation, since that's not what the original used
    • simulated the 68701 MCU
    • enemy movement should now be correct (bublbobl36rc2yel)
    • fixed clock item behaviour. Now enemies start moving again after 10 seconds (bublbobl36b3yel)
    • supported coin lockout
    • emulated the boblbobl protection device, getting rid of the ROM patches.
    • adjusted PSG volume in tokio (tokiob067gre)
  • Brian Troha fixed the gaplus driver to use its samples
  • Nathan Woods fixed the undocumented bit test opcodes in hd6309 cpu core
  • Nathan Woods did some i386 cpu core fixes:
    • Fixed algorithm for identifying 32-bit segments
    • Near branches now won't force a segment reload
    • Implemented RET imm16 under 16-bit mode
    • Fixed SBB instruction (the borrow was deducted from the second operand, not the result)
    • Fixed LDS, LSS, LES, LFS, LGS under 32-bit mode
    • Partially implemented LLDT, LTR, CLTS, WAIT and MOV dr instructions
  • Nathan Woods renamed arcadia machine/vidhrdw/include files from arcadia.* to amiga.*
  • chaneman fixed Vs. Stroke & Match Golf name
  • Angelo Salese did some ST-V fixes:
    • Fixed various DMA bugs, including a missing save/update mode in indirect mode and added a default add value for the A-Bus transfer, to avoid strange uploads.
    • Further improved the SCU emulation, added two unemulated irqs (PAD and SCSP), improved the "illegal" DMA operations and started to work out with the games headers.
  • Pierpaolo Prazzoli and Tomasz Slanina submitted Hyperstone cpu core fixes:
    • Added and fixed the timer and removed the hack
    • Fixed delayed branching for delay instructions longer than 2 bytes
  • ElSemi added SE3208 cpu core emulation
  • R. Belmont fixed a itech32 driver crash on AMD64 cpus
  • Kenneth Miller fixed the namco54 sound driver compiling in VisualC++
