0.86

----

 

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:

src/inptport.h:

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.
