Version 0.86 "Virtua Fighter"

Released: 2004-08-22

While there are no new working games in this release it remains interesting from a technical and development point of view mainly due to the new PPC core as well as the Hyperstone and 37710 fixes. It should also be a fairly stable release after the many input changes which have taken place recently.

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

General Improvements

This makes the parser deal with .toc files output by current cdrdao better. I need to just give in and rewrite it for 2-pass operation sometime, it'll be much cleaner then.

Incidentally, if anyone has any idea where to get specs for e.g. CloneCD or some other popularish image format(s) let me know and I'll add support.
