Mame v0.86

RBM-13s, 09:33, 23-08-2004

Только в сети появилась версия 0.85u3, как сразу же вышла оффициальная:

Driver Improvements:
- M37710, NamcoSS22 and C352 improvements [R.Belmont]
  - M37710 changes (m37710.diff):
    - Data bus is actually 16 bit, not 8
    - Fixed saving of status register on interrupts
    - Fixed errors in PHB, PHT, PLT, and ANDB opcodes
    - Added XAB, PLB, and ROLB opcodes
    - Fixed IRQ dispatch errors
    - Various get_info fixes
  - NamcoSS22 changes (s22.diff):
    - All CPU clocks changed to measured-by-Guru values
    - Handle the changed M37710 bus width
    - Temporarily disconnect shared RAM. There's a problem where the 68020's shared RAM test wipes out the 37710's work variables and causes it to crash. I suspect there's a register that halts or resets the 37710. (note: Prop Cycle has no POST and doesn't cause this problem, but all the other games do).
  - C352 change (c352.diff):
    - Remove debug printf that accidentally snuck in
- SPI Improvements [Ville Linde]
  - Improved (but not yet correct) tilemap decryption
  - Preliminary sprite priority support
- PowerPC 403 core [Ville Linde, Bart Trzynadlowski, Stefano Teso] This is basically SuperModel (Sega Model 3 emu)'s PPC core minus the FPU and 6xx-series specific instructions (that stuff isn't ported to MAME yet). As such, it's passed all manner of synthetic PPC torture tests and should be quite reliable for any PPC403-based hardware.
- Virtua Racing improvements [Olivier Galibert, Andrew Gardner]
- Hyperstone CPU Core Improvements [Tomasz Slanina, Pierpaolo Prazzoli]
  - Tomasz Slanina
    - interrputs after call and before frame are prohibited now
    - emulation of FCR register
    - Floating point opcodes (preliminary)
    - Fixed stack addressing in RET/FRAME opcodes
    - Fixed bug in SET_RS macro
    - Fixed bug in return opcode (S flag)
    - Added C/N flags calculation in add/adc/addi/adds/addsi and some shift opcodes
    - Added writeback to ROL
    - Fixed ROL/SAR/SARD/SHR/SHRD/SHL/SHLD opcode decoding (Local/Global regs)
    - Fixed I and T flag in RET opcode
    - Fixed XX/XM opcodes
    - Fixed MOV opcode, when RD = PC
    - Fixed execute_trap()
    - Fixed ST opcodes, when when RS = SR
    - Added interrupts
    - Fixed I/O addressing
  - Pierpaolo Prazzoli
    - Fixed fetch
    - Fixed decode of e132xs_xm opcode
    - Fixed 7 bits difference number in FRAME / RET instructions
    - Some debbugger fixes
    - Added generic registers decode function
    - Some other little fixes.
- Jaleco Mahjong Driver update [Angelo Salese] some games are *almost* playable but still have protection issues
- Adjusted Top Speed volume balance
Changes to the main program:
- Misc Fixes [Nathan Woods]
  - Fixes PORT_INCLUDE by making the final IPT_END appended within input_port_allocate()
  - Added some MESS specific defaults
  - Spelling fix in IPT_BILL default
- Fixed some Multisession win32 bugs [Chris Kirmse]

Добавили очереной клон:

Field Goal (different) [Andy Welburn]

И кучу неработающих игрушек:

Various Konami PPC based games [Ville Linde]
- GTI Club
- Gradius 4: Fukkatsu
- Silent Scope
- Silent Scope 2
- Racing Jam
- Racing Jam: Chapter 2
- Thrill Drive
- Midnight Run
- Winding Heat
These are to demonstrate the PPC core in action, they contain only very preliminary emulation and do nothing more than display the initial test screens.
Cool Riders [David Haywood] skeleton driver, to be continued at a later date
Pit Boss added to merit driver, not investigated the issues yet
Tatakae! Big Fighter [Tomasz Slanina] serious protection issues
Cool Mini Hyperstone based game, incomplete set
