Specific Contributions

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

• R.Belmont and Tomasz Slanina added sound in the ST0016 driver: Neratte Chu & Renju Kizoku now have sound

• Lawrence Gold made some misc Cleanups

• smf fixed a couple of issues with hard disks without checksums

• Brian Troha corrected DIP switches for Karate Blazers, Turbo Force, Raiden 2

• Barry Rodewald and GreyRogue made Megaplay improvements

• Ville Linde updated the SPI / 386 drivers:
  • Added the missing keys to E-Jan
  • Added layer enable register
  • Wrote a new i386 disassembler. Dasm386 wasn't always showing stuff correctly, and now the i386 core can be compiled without i86.
  • Preliminary Dallas DS2404 (RTC/CMOS) emulation
  • Added 93C46 eeprom to RF2 single and RF2 2K. It's not hooked up though.
  • Improved i386/z80 interleaving. This should help with the small pauses.
  • Fixed some stuff in the i386 core. These don't seem to affect the SPI games, but should help with MESS

• Nathan Woods improved i386:
  • Added a check enabled when MAME_DEBUG is defined that raises an error if the CPU core executed a negative cycle count
  • Fixed a bug in i386_set_info() when changing the EIP register
  • Fixed some compilation errors under non-GCC compilers
  • Implemented ES, BOUND, DAA, DAS, AAS, INSB, INSW, OUTSB, OUTSW, LES, LDS, HLT, LSS, LFS, LGS, IMUL with a 32 bit adjustment,

• Ville Linde improved the i386 core:
  • added DS and SS segment prefixes. renamed fs,gs -> segment_FS, segment_GS
  • added INTO opcode
  • regression tested and fixed AAS opcode (incorrect behavior in Intel docs)
  • added AAA opcode (with correct behavior)
  • added AAD and AAM opcodes
  • added CMC opcode
  • added SETALC opcode which is undocumented
  • removed a non-existing PUSH8 opcode from groupFE_8.
  • regression tested and fixed SHLD and SHRD opcodes
  • fixed AF flag calculation
  • fixed AF flag in SUB and DEC opcodes

• smf made Beatorizer (bootleg) improvements
