Specific Contributions

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

• Aaron Giles, Gerald, and Thierry fixed sound in Desert Breaker with new roms

• Brian Troha fixed dip-switches in the nmk16 driver

• 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.

• Juergen Buchmueller fixed a crash in i8x41 cpu core reading uninitialized internal RAM

• 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

• Lawrence Gold fixed some C89 compiler problems

• Nathan Woods renamed arcadia machine/vidhrdw/include files from arcadia.* to amiga.*

• chaneman fixed Vs. Stroke & Match Golf name

• Pierpaolo Prazzoli fixed oisipuzl inputs

• Nicola Salmoria fixed the Rainbow Islands visible area

• 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.

• Angelo Salese fixed a disassembler bug with the NEC cpu core

• Hans Andersson fixed player 2 and 3 inputs in xenophob

• Nicola Salmoria fixed the sound banking in taito_f3 driver

• Nicola Salmoria fixed memory leaking and added a check in debug builds

• 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

• chaneman and Pierpaolo Prazzoli fixed colors and Cocktail support in Enigma 2

• ElSemi added SE3208 cpu core emulation

• Robert Alan Byer fixed a model1 driver compiling problem with OpenVMS

• R. Belmont fixed a itech32 driver crash on AMD64 cpus

• Kenneth Miller fixed the namco54 sound driver compiling in VisualC++
